I have a 87 GN and the torque convertor won't lock up. When i ground the F terminal on the ALDL connector it will lock up, when i tap on the brake pedal it unlocks. The transmission and the brake switch seem to be working fine.What else could i check? Thanks ..
I have seen this problem in this forum before. I read that the solenoid for the converter will stick, and it is generaly a good idea to replace it when you have transmission work done. Hope this info helps.
Might want to hook up a scan tool and see what your ECM thinks. If its getting incorrect gear, Park/Neutral switch, or VSS (speed) information, it may not be commanding the TCC to lock up.
Thanks for the replys. I was exploring gnttype.org and saw something about a vehicle speed sensor (VSS) and got to thinking about it then i thought about the fact that i have a 145 speedo conversion with the reducer. I took that off and the convertor locks up fine. Now i need to get my speedo calibrated so that i can throw that D**N recucer away. Thanks.
