I've posted that in someone elses thread earlier, but i probably should have started a new thread to receive more answers. so here we go
2001.5 passat 1.8t, awm, auto tranny, sedan, 190k miles
Underwent Unitronic Stage 2 software update around 6 months ago
would a faulty TC ...F-O-R ....S-U-R-E... throw a code? after all it is just a mechanical part, without anything electrical to it so how would the ECU know that there is soemthing wrong with it?
i mean, i've researched TC and nowehre it says that if a TC is faulty you'll get a code, but rather some type of relay inside of transmission, solenoid or whatever.
im asking because my transmission has been slipping recently on acceleration. it loses its grip around 4000rpms on 2nd gear, rpm's go up because im pressing on the pedal so rpm's keep going up without any acceleration , like on neutral (it all heppens very quickly) and tranny shifts to the next, 3rd gear, and the story repeats itself from 3rd to 4th. On both shifts the car jerks a lot, oftentimes the transmission locks in one gear, all of the marks on the cluster (P,R,N,D,4,3,2) light up and i have to restart the engine to reset it. I've also heard that it's sort of a defensive system that prevents the tranny from breaking completely. It is not low oil because i've checked that already and it is fine
This is why i was suspecting torque converter after all the research i've done but i dont have any codes. TC throwing a code is only talked about on this forum, i havent found that information on many others. As a matter of fact, other forums say the opposite. Could you guys confirm?
