Your problem seems like the n92 solenoid. Sorry, it doesn't answer your question but if I had your problem that is the one I would change.
I have an 02 jetta VR6 24v with the 5 speed tiptronic transmission. For the past several weeks, the car will not shift out of first gear unless I let the car warm up for 10 - 15 min. Even then, it may make it to 2nd or 3rd gear but never shift to 4th for up to 30 min of driving.
I dropped the car off at my mechanic and he is advising that we replace the transmission. I feel this is overkill, as shifting is the only issue with the transmission. There is absolutely no slippage.
I do have the bently and have been reading up on solenoid valves and the valve body. Is there anyway to verify if any of my solenoids are failing, or if replacing the entire valve body would remedy this issue?
I do not have the cash reserves to replace the entire transmission right now as I am in the middle of a move. Any help appreciated.
Have you looked at your fluid? Never trust any one mechanic when they tell you your transmission needs to be replaced. ALWAYS get a second opinion, and maybe even a third. Im a transmission mechanic and I cant tell you how many times Ive had customers come in that have had their cars in other shops that said they needed a new transmission, and it turned out to be a $50 solenoid or it just needed a service and additive. I would take it to a transmission shop first before you replace anything, but if they tell you its one or more solenoids then it would be cheaper to change them yourself if you have the mechanical knowledge.
Best thing to do is to change the fluid, use mercon 5 full synthetic, no need for the original VW stuff, if no improvement, replace the entire valve body. I work with these transmissions often and have found the valvebody assembly to be the cause of this erratic behavior on these transmissions. Small particles in the fluid greatly contribute to premature failure of the valvebody, that is why the atf should be replaced every 35 to 40 thousand miles. I have a new rebuilt and upgraded, Valvebody for a 09a Jatco Tiptronic Transmission. All solenoids are new and has a 1 year warranty from the manufacturer. I never got to install it since I decided to go with a 6 speed swap. I'm asking $700 with free shipping anywhere in the U.S.
I have read a little more in my bentley and base on the comments here, I am going to do the resistance test on all of the valvebody solenoids.
If they all test out fine, I am just going to buy another car.
I cant justify the expense of fixing this car anymore.

The best way to do it is to locate a junkyard that will sell you the whole kit, try not to buy all the parts separately as this might be more expensive, time consuming and a real headache. You will also need to get a good reliable technician. If you are interested, I can get you a whole kit. They run between 1800 and 2000. Everything included, ie: tranny,shifter,clutch kit,sensors,pump, etc... If you think that is better to sell the car than to fix it, sell it. Remember, the transmission is only one of many systems, if you spend 3k fixing one part, you are not making the whole car new...
well I got my car back from my tech and the diagnostic code pulled from the transmission was
00652 - gear monitoring, implausible signal, mechanical malfunction
cluctch or valve body faulty
i am not thinking this is a solenoid issue anymore.
That code is telling you that there is clutch slippage. The valve body needs to be removed and inspected by a specialist, if particles are found inside it, the whole transmission will need to be taken apart and PROPERLY overhauled including the torque converter. You are looking at over 3k for this repair. Do not take it to AAMCO or other mediocre place. The repair will need to be backed by a written LIFETIME WARRANTY, if not, run...
yeah, that is not happening.
I will finish paying this car off, then sell it as is. and get what I can for it.
I have been looking more into the 6-speed swap, but I just dont see the point. There are many other painful failures that can happen other than the transmission.
Well, if the math is to your advantage... I paid 2k for my 2003 jetta 1.8t with 70k miles. The reason I paid that cheap? My customer decided that it was better to get whatever amount for it than to have it fixed, her loss was my gain, but then again, I specialize on these cars... Do not give up on it man, all cars will have some kind of problem sooner or later, some more than others, that is why I love my profession. If you need need parts for that transmission, let me know, I have plenty of good used parts for them...
I had a transmission problem with my Jetta. It would not shift out of first gear until I drove it around to let it warm up for about 10 - 15 minutes. Then it would start shifting fine. After I installed a new N92 solenoid, the shifting problem went away. Now it shifts just fine with no warm up necessary.
my daughter has a 2002 gti 1.8t with eyp trans. it has been a problematic trans since she bought the car 5 years ago.it always really banged into 3rd gear (sometimes)we went to vw as the car still had warranty and they tried many different downloads and even put in a new valve body but it would still on occasion bang into 3rd.
then the trans oil cooler failed and overfilled the cooling system,i am a licenced h.d.mech. and she is broke so guess who painfully cleaned and flushed the cooling system and the trans.many many times to clean everything up.i have the stock oil in it and we keep getting the 00652 gear monitoring code intermittent. we clear it and sometimes the car drives like the pride of the fatherland.but the you come to a light and drive off and it won't shift into 3rd(unless you back your foot off and wait)it won't shift up in tiptronic either when this happens.
I have hard a hard shift into fourth for a while. Dealer replaced valve body although I was pushing for the entire trans. Valve body helped alot but still have the occasional mini jolt. Just had the fluid drained and refilled and that helped give new life to the transmission. Have you checked for fluid leaks/fluid level?
Look in the faq
Auto trans fluid change or flush will not make a trans fail. Stop spreading the wives tale/urban myth.
