My 1989 Bonneville seems to be having a transmission problem. The other day I pulled up to a stop sign on a slight incline and took my foot of the brake and car acted as if it wanted to keep going. It felt like it was surging. My question is could this have something to do with the TCC solenoid and if so where do I located this thing on my car as my manuel doesn't mention it. The TCC locks and unlocks fine on the highway and i've only had this problem a couple of times. I recently had my transmission filter and fluid changed thinking this might help solve the problem. The car is great otherwise but this has got me stumped. With 198.000 on the car i'm figuring it'* about time for a transmission failure of somekind. Thanks for the help.
