91 legacy TCU location

Featured Replies

I am asking for my brother in law since he has no internet.

Here is the thing, He bought the car ( automatic) and was great for months then it started to shift down once in a while even though he was maintaining a steady speed. fast forward. Now the car will not go into top gear at all and so has been parked pending further diagnosis and repair. The original tranny was flushed and filled with new filters .no joy.

REplaced tranny with a known good auto tranny with same gearing and still the same so I must assume it is the tcu and have no idea where to find it and really dont know what it looks like anyway. I would love to give him a little good news help.

I actually had to do a bit of custom wiring on mine, so I can point you in the right direction. It should be right under the dash near the steering column. It isn't the one with a but load of wires, but the one that makes a "T" with the ECU. There should be a 8x2 (bigger of the three), 6x2 and a 10x2 clip that goes to it. Hope this helps, and best of luck!

Thank you. I am sure it will since now I know where to look while running the local yards.
