Hey guys,
Can someone please scan in the diagrams of the Tranny ECU ports for a 1991 TR 4 cylinder. Thanks!

Also where is the actual tranny ecu located, i know where the ECU is,but havn't really noticed the tranny ecu. Thanks.

Did your TCM die?

if your goin 2 replace it, get your tranny serviced aswell, myt was running a treat after i had it done.

dude....go and a buy gregories manual....they're like $20-$40 depending how hard u look.

it'll save u asking alot of questions which the book can easily answer aswell.

The tranny computer is built into the ECU itself.

yeh i thought it was all in one.
go buy a manual. i got the gregories for $30 when k-mart had a sale. best thing ive bought in usefullness for the car. lol

In Secon gen the TCU is located under the console up under the radio, it will be fairly easy to find.

Only on TE onwards are the TCU part of the ECU
