'91 Q45 - Transmission Self-diagnosis code

Post by **silverQ** » Fri Apr 13, 2007 7:19 pm

Well I ran the self-diagnosis and got a code "A". Does anyone know what that means. Symptoms are no go when cold for like 60 secs. and sometimes at 45MPH+ I get a kinda small vibration going on. THX

Per FSM "A" means turbine sensor discoed or shorted [no signal to TCU].

Common failure from acidic ATF eating into sensor seals and shorting sensor. ATF travels down sensor cable and leaks out the electrical connector on rear of transmission.

The judgement is "A".

Turbine revolution sensor circuit is short-circuited or disconnected.

Go to the following site and download a copy of the Factory Service Manual for 1994:

I got Code D. Something about a battery. My car battery? Or TCU battery?
