SOURCE: Audi a4 autotransmission change fluid

The automatic cars (at least the tiptronics, which came out in 98) require the transmission to be up to a specific temperature, which must be monitored while changing the fluid - this requires VagCom, the VW/Audi diagnostic software (I'm not making this up). I am not sure whether the non-tiptronic cars had to have this as well or if it can be done as any other transmission - best bet is to call a European specialty mechanic and ask them - a dealer will kill you with labor rates. Do not just drain and refill though, without finding out first whether the VagCom procedure must be used.

SOURCE: 1997 Chevy 1500 P/U 4x4 small V8. Transmission shifting issue.

you may be confusing the torque converter clutch engagement with o.d. this trans has a problem with the T.C.C. regulator valve wearing out the valve body bore. this will cause the converter clutch to engage only sometimes or not at all. this will set a P1870 code in the control module. when this code is stored in the controller, ( check engine light may or may not be on), it increases the pressure in the transmission causing the 1-2 shift to be harsh. ask a local tranny shop to scan the vehicle ( most will do this for free) if this is the problem they can either fix your valve body (sonnax parts) or replace it with an upgraded valve body. hope this helps

I need a little mor info. But the reason for the being stuck in 2nd gear is because when something goes wrong with the tranny. it goes into "LIMP" mode wich keeps the trans. from shifting out of 2nd when you are going forward. It does sound like your trans. is gone out though.

2010 Jeep Wrangler unlimited sport extreme shudder at 40 mph- if I press the gas-pedal and get the RPMs to rev, the shudder ceases, only to return once I am back down around 38 mph-41mph.


which engine the 3.6? v6?
that shudder is called MISFIRE.
get a tune up yet, even $1.49 spark plugs?
no its not the trans,
if it dont slip, its not trans, (see RPM races? that is slip or too low gear)
if it shifting to the right gears, its not the trans can you count them?
is the CEL lamp glowing or flashing driving, is yes, that means
scan me now. in fact scanning while it shudders, is like (magic)
why start guessing, do a tuneup,
then scan it.
if its is misfire the PCM will tell you what cylinder misfires.

are your spark plugs 6 years old, if yes, why?
going for 200k miles on them.?

My bmw 318i 2003 is not responding to the automatic gear liver. it doesnt move.


BMWs in the 3 Series and 5 Series that come with the 5-speed ZF transmission commonly experience problems with torque converter delamination. Drivers will notice signs of this problem when the car appears to shudder or misfire at around 40-50km/h.
This BMW transmission problem needs to be repaired as soon as the first signs are noticed. If you drive until the converter lining actually fails, it can destroy the entire pump assembly in the transmission. This will require a complete reconditioning of the automatic transmission.
BMW drivers are cautioned that it is better to spend a little now, rather than a lot later.
Apart from the problem with the torque converter delaminating, these 5-speed transmissions commonly suffer breakage of the D/G cylinder. If this breaks, the car loses reverse gear. This automatic transmission problem is another that requires a total transmission overhaul to repair.

Hi there,

You definately have a transmission problem.

When was the last time the transmission fluid was completely replaced? Trans fluid is CRITICAL for proper shifting operation. The measuring of trans fluid is also critical and must be measured in a certain way (engine warm, selector moved through all gears, then finally left in N, while checking for hot level).

Your trans also has a fail-safe function - when a fault is detected, the trans will go into "LIMP" mode. This still allows driving, but will usually remain in 3rd gear. In this instance, the "N" (Neutral) light on your dash may also flash.

If you are technically inclined, I can provide your with instructions on how to check your trans computer for fault codes...

Let me know...

My 2003 envoy will not engage reverse slips into second gear and will not engage overdrive.. It gave no warning signs of transmission failure.. What is the problem??


It could be a bad transmission sensor, but the check engine light must be on, if it's this way take it to an speciallist to connect the scanner and this will tell you what is wrong with the transmission.

There may be a problem with your transmission and the way your car is shifting. Take it to a shop and get it checked out.

Sure sounds like a slipping transmission to me. When is the last time you changed the transmission fluid? Before you go dumping $2,600 for a new transmission, I'd do a transmission fluid change first. If you do change the fluid, use Dextron 6, it's GM's new transmission fluid, much better than the fluid you have now. Not to scare you, but my transmission went out at about 100k miles, so you're doing good if it hasn't been rebuilt yet.
