Drove 55mph on Second Gear Will Damage Automatic Transmission UPDATED

What you are supposed to know about your ZF6HP26, 6HP19, 6HP28 and similar ford Transmissions.

6hp26Z_main

It applies to all BMW, Jaguar, Bentley, Rolls Royce, Maserati, Audi and others with ZF 6HP26, 6HP19, 6HP28 In this mail service i will be explaining why yous have manual issues like: -harsh shift two-1 -not able to shift into park when hot -weak torque feeling -gear speed ratio faults -other faults All highlighted problems you can experience even on low miles cars less than seventy-80k, information technology depends on at what speeds your car mostly runs. On the highway this tranny will easily last 200-300kmls. AND EVERYTHING IS RELATED TO VALVE Torso Force per unit area LOSS DUE TO SOLENOIDS OR ACTUAL VALVE BODY SEALING GASKETS LEAKING Within, BUT BETTER Practice BOTH. DRIVING WITH LEAKING VALVE BODY WILL Somewhen WEAR OUT ACTUAL TRANSMISSION HARDWARE. BEST ADVICE FOR YOU: SINCE 99% bug with this trannies are related to valve body fluid force per unit area loss, I strongly recommend new (re manufactured) valve body from ZF (expensive 1600$), (yous tin find some companies offering this rebuild, simply they charge nearly new VB cost, or rebuild it yourself with NEW SOLENOIDS PACK (300-400$) and SONNAX cypher kit (150$) . If after you rebuilt or replaced valve torso and R ESET ADAPTATIONS USING BMW SOFTWARE INPA OR ISTA IS A MUST, OR You WON'T SEE Whatever DIFFERENCE AFTER REBUILT, Because TCM KNOWS VALVE BODY Pressure level VALUES AND THEY MUST BE RESET. IF After REBUILT, information technology's not shifting well, it means You lot WAITED Besides LONG WITH VALVE Trunk REBUILT AND DESTROYED transmission hardware (bushings or bodily clutches failed) and you need to rebuild it, but like i said master problem STARTS at valve trunk and then if non fixed in fourth dimension y'all get worn out manual. All those jolts, bumps or harsh shifts cause premature wearable and tear on your tranny. Rule of the pollex is not to bulldoze it if information technology jerks,or shifts wrong. replacing but solenoids without rebuilding valve body, where accumulators/pistons ever go bad after 60-70k, will non go y'all perfect results, only might better shifting quality. Recollect-cheap people usually pay twice (no offense). So y'all detest the way tranny shifts and dealer and other shops didn't discover any faults and told youit is what information technology is and this is how information technology is intended to work! Well it is total lie they are trying to go rid of you lot with. In fact ZF 6HP26 6hp19, 6hp28 is a very good transmission, powerful, bullet proof pretty much if serviced in time and proper fluid force per unit area maintained! This tranny is still considered i of the best and has carbon clutches vs cheap paper ones y'all can detect on Japanese cars. But this tranny has very serious and very of import weak spots you accept to take care of: -Start matter first check tranny temperatures. If it is higher than 95C, so most likely you have a problem with tranny cooling system or your engine cooling has some leaks causing running it very hot. 6hp26_temps Usually loftier temps indicate following:

ane) engine cooling arrangement problem- air bauble or airlock 2) if everything is skillful with cooling organisation, check your tranny oil libation- information technology gets chock-full up pretty ofttimes and also indicates that some clutches or TC clutch is worn out and that debris clogged oil cooler. iii) worn out TC clutch slipping overheating manual fluid. Your good engine temps are 103-105C and if it climbs to 107-110C in traffic, it means you've got a leak : -lower radiator hose sensor leaking (usually shows a white balance effectually the sensor) -valley pan under intake -rear cover plate betwixt tranny and engine. Very mutual later on 100k or eight-10yrs. -coolant tank cracked -radiator cap leaking pressure -coolant pipe seal leaking -other cooling issues It is very important to go on temps in specs not only because of few degrees, but because with leaking cooling system yous lose coolant pressure introducing air in the system, causing uneven cooling and overheating both engine and tranny. Good OEM specs are 103-105 bicycle when idling and lower hose should exist hot around 60-80C. When you drive it tstat is controlled by ECU therefore it keeps information technology cool on the thruway. Easy way to examination your cooling system 1) Disconnect aux pump connector assuming aux pump is working (they fail often) two) Drive your auto to warm engine well

Turn on heater on hot only low speed
check if you get hot air from vents for 10 minutes.
If subsequently a minute you noticed your heater is not hot anymore, it ways y'all've got a leak!
This Engine has self bleeding cooling organization, which means you cannot get air pocket if arrangement is well sealed.

So if engine temps are adept and tranny notwithstanding runs hot 100-110, it means heat exchanger is chock-full with tranny clutches, TC wearable and tear dirt. Supplant it and check if it got better. This tranny will dice quick if temps are not proficient. -MECHATRONIC ADAPTER SEAL. mech_adapyter This adapter (number 2) commonly lasts merely 60-70kmls (BMW lifetime). Replace it every 60kmls fifty-fifty if tranny shifts well. It is very important because information technology keeps your mechatronic valve body under specified pressure therefore it controls how clutches are pressed! Which means if your gasket is weak your tranny clutches are not pressing well on each other causing premature wearable and tear, also tranny pump and TC clutch will be affected. This square seal also can Crack, in this case you volition get tranny fail safe errors and even clutches slipping ERRORS, causing very quick TRANNY Death. DON'T DRIVE YOUR CAR IF You lot'RE GETTING Whatsoever TRANNY FAULTS, EVEN After RESTART TRANNY ERRORS GO AWAY FOR A WHILE, IT IS NOT A TRANNY Computer GLITCH!!! http://world wide web.thectsc.com/products/mechatronic-seal-adapter-6hp26-6hp28-6hp32-42-52.html YES THIS SMALL, Inexpensive GASKET CAN Damage YOUR Transmission PRETTY BAD. -OTHER four Safety PIPE SEALS. 6hp26Z_selas They 5,half-dozen,7 besides control clutch pressure level, but fifty-fifty if they are flattened pretty bad transmission won't requite you any errors. Its always good thought to supervene upon information technology- yous'll observe a difference how your tranny shifts. Www.RMEUROPEAN.COM has these seals under transmission parts department. -SOLENOID KITS. 2 TYPES solenoids_2 -Well-nigh COMMON E65, YOU DON'T NEED PARKING SOLENOIDS SINCE THEY DON'T Go BAD Often, SO YOU CAN USE M-SHIFT SOLENOIDS, BUT YOU Tin GET East-SHIFT PACK As WELL, WHICH IS 200$ More. http://www.thectsc.com/products/solenoid-kit-6hp19/26/32-thousand-shift-36-45.html solnoid_pack Yep they go bad and are non simple solenoids you used to know from sometime school trannies. Now these are pressure regulators and they exercise not only work open up\close operation, they control pressure level and after so me time they get chock-full, overheat, etc. So if your tranny temps are good and your tranny shifts hard, it could be your solenoids. Its good idea to replace them every 100k, because they control everything in the tranny. You volition be surprised how tranny shifts with new solenoids. And you lot don't demand 2 parking solenoids, so you can use 200$ cheaper kit, which fits five,half-dozen series without E-SHIFT. Also dont be scared if y'all open your transmision and find out that color is non the same- relax it inverse color because of temps and age. In that location are two types of kitsAll the parts at very practiced prices can be found here: http://www.thectsc.com/catalog/mechatronic-parts-52.html -GUIBO FLEX DISC. They normally go bad subsequently BMW lifetime period sixty-70k. Common Symptoms: a) hard ii-1 sift b) at stop you tin hear clunking when shifting from P-R-D c)overall tranny shifting quality -Tranny fluid level. oil_pan_metal Yeah due to leaking oil pan gasket you might loose some fluid. E'er cheque tranny oil pan for leaks and tranny fluid level (use BMW sealed tranny fluid level check procedure). Information technology is always meliorate to install metal oil pan- it never leaks and cheaper to maintain! You can add together BMW OEM PENTOSIN brand fluid or you can use MOBIL1 or CASTROL synthetic ATF fluid (10$/qt) import multi vehicle formula, believe it or not it has aforementioned specs if not better than BMW fluid and works great. Tested for 160kmls. BMW volition only recommend OEM FLUID of course, but its upwards to you, so delight do not comment here that unlike than OEM fluid will kill the tranny. But always make sure it has the aforementioned specs of course. Mostly Dextron 6 fluid applies every bit well for this trannies. UPDATE: Manual RUNS MUCH Better WITH OEM ZF FLUID OR Beat M1375.4 FLUIDS, SO Amend SPEND FEW MORE BUCKS FOR CORRECT FLUID. FEBI OR ZF Will Piece of work Corking. SOME Use FORD FLUID, SINCE ITS THE Aforementioned Transmission BUT FLUID IS MUCH CHEAPER. -Torque converter clutch. Yes it tin go bad but like any clutch, considering this tranny engages this clutch very early on causing premature wear and tear. In sport mode information technology can engage clutch as early as at first gear!! That's why nosotros get decent mpg from this tranny. In other words it is more similar a transmission tranny with torque converter working merely at very low speeds and low rpm. And then I would not recommend driving it very aggressively in the city, unless you lot enjoy paying 4-5k for a new tranny. Don't forget this tranny handles 300-400hp and some impressive torque. Driving in normal way, TC can final up to 300kmls!! most common symptoms of bad clutch: -sometimes when clutch is very bad it volition throw 1721 error clucth slip -bad MPG. Without TC clutch your car is all the same driveable, but you tin can experience its very weak even though engine feels strong -later fourth gear tachometer arrow is not steady -weak pickups, downshifting when driving uphill -bad slipping clutch will overheat tranny pump and finally will impale internal tranny parts (clucths, valve body, seals, etc) good news you tin have your TC rebuilt for effectually 300$ and from personal experience i must say its not as perfect every bit new, just decent still. Important Notation: DON'T FORGET TO RESET TRANSMISSION ADAPTATIONS Subsequently Whatever REPAIR Done ON THE Manual!!! IF YOU DON'T RESET Information technology, TRANNY WON'T SHIFT Whatever Meliorate Because It REMEMBERS BAD VALUES. SOME PPL THINK PRESSING GAS PEDAL AND Saying SOME MAGIC WORDS RESETS TRANSMISSIONS EGS ADAPTATIONS IS A Full Made Up JOKE. YOU CAN But RESET It WITH BMW SOFTWARE INPA, ISTA, AND SOME OTHER SOFTWARE SNAP ON ETC. I know its a long listing of issues, but if y'all take intendance of your tranny every 80-100kmls it pays for itself pretty skillful. Most important thing for this tranny is correct fluid force per unit area and temps, other parts like clutches are very durable and made with highest quality standard. Don't forget the aforementioned tranny they still install on newest Bentley, Rolls Royce, Audi, Maserati and other luxury brands. This tranny is way more reliable than Mercedes one or Lexus trannies with same specs.
