- 14 JSW DSG, 03 Wagon 01M, 400k and IPT performance auto!
2001 Jetta TDI with the 4-spd auto, 01M transmission. 109k on the car. In the last few thousand miles or so, mostly in the afternoon when the car had been sitting for many hours (so it was stone cold, but not "overnight" cold) I would start up and attempt to drive away. Sometimes it would accelerate normally, but MANY times (and getting progressively worse up until 2 weeks ago) the car would get up to about 20-25mph... And all the power would just vanish. The tranny would NOT shift when it was supposed to, so I'm doing 30mph at 3000 rpm with my foot to the floor. Usually traffic would force me to stop before it would clear itself, but when it cleared, it would be like flipping a switch. Just that fast, the car would decide "I'm better now" and suddenly accelerate rapidly, and start shifting again.
Of course when all this started getting really bad, thats when my VAG-COM cable died. Perfect timing. I just got a new VAG cable, and confirmed one suspicion from a code: The MAF had been acting strangely. I replaced the MAF with a 2.0 MAF 2 weeks ago, and the car has been mostly normal since. It seemed to partially lose power again one or two times since, in the last couple days. I just got the new cable today. In pulling the codes tonight, I found this code in the transmission:
01192 Torque Converter lock-up clutch
04-10 Mechanical Malfunction - Intermittent
What (if anything) should I do about this? The only possible slippage I can think of is when the car was in it's "low-power" mode, but its not doing that as much right now. Also, does this tranny lockup in all forward gears? Can I make it do this?
NEW INFO: Today it started pulling this crap again, but there is NO corresponding code in the transmission ECU. Now I'm really lost. The MAF was replaced with one that I had as a spare. (altho it IS a 2.0 MAF, the airflow numbers were the same as the original TDI MAF when I bought it) The problem seemed to vanish for 2 solid weeks, and now it is back again. HELP PLEASE! I cannot afford to be like a stealership, and just throw extremely expensive parts at the problem.
I did some checking with the VAG, and while the car was acting stupid, the Tranny ECU was reporting very-slow-to-change clutch slip numbers of between 275-600 while the car was at 45mph and my foot was on the floor. Car in third gear (not shifting) and tach was pushing 3000+.
Oil and Tranny Fluid was changed about 1500 miles ago. Tranny now has Mobil One Fully Snythetic ATF inside. Pan magnet did NOT have anything beyond a light coating of steel slime, quite normal (IMHO) for a 107k tranny.
Soo.... Any suggestions?
