Having a problem I need to get some info on. If anyone can give an answer, it would be much appreciated. Please reply via email as well as the boards, as my server doesn't keep a lot of messages, it seems.
2003 Buick Century 3.1L V6 with 4 spd automatic trans, 119,000 milesRecently started shifting hard at times, not constant. When I had the oil changed last weekend I had the trans fluid changed as well. Started shifting harder, but again not constant. Yesterday on the way home, it started shifting extremely hard, shaking the car in 1-2-3 and banging into and out of 4th. Got it home and checked tranny fluid, it was a bit overfilled, but not incredibly so. Parked it for the nightand borrowed my daughter's car. Talked to a good friend who is a Jaguar Service Manager, he told me the controller (computer) may need reset, and recommended Lucas anti-slip additive as a temporary measure. He said the overfill on the hydraulic fluid wouldn't hurt anything. I did the computer reset, no change at all, just had to reset the clock and the presets on the radio. Took it back to the shop that did the fluid change when they opened this morning, they checked and agreed the fluid was high, drew out the excess and added the lucas in for me. No change, maybe a little softer shift, but after a 15 mile test drive it was back to square one. Also started noticing that when it downshifts from 2nd to 1st, the car feels like its on a bumpy road for just the time it takes to shift (which is 2-3 seconds since this started getting worse) Then the Service Engine Soon light came on, so on the way home from test driving, I stopped at Autozone and had them put their tester on it. Not sure of the code #, but it said "Torque Converter Circuit Stuck Open". ??? I called Jon (Jag man) andhe said he had never heard of this code but would look it up and let me know what he finds. I've Googled it a few different ways and can find nothing, and in the GM trouble codes, this verbage doesn't show up. I'll call the dealer on Monday,but in the meantime, wondering if anyone can shed some light on this? Could the trouble code be causing the slippage and hard shifting? Or the hard shifting and slipping cause the trouble code? Am I about to invest in a new or rebuilt tranny? The hopeful answer here is NO! Any help much appreciated
