| Post subject: | Need help diagnosing a trans issue |
So I finally got my torque converter installed and got everything back together. Let me back up a little. I had some slippage and a rare grabbing and stalling at low RPM when initially shifting into D or R. Or when the trans downshifted to first at low RPM (like foot off the go pedal when rolling up to a stop sign). The grab only happened about 3 times over several weeks just prior to me parking the thing until I could get enough cash for parts and then to find the time to do the job. I assumed that the grabbing issue was also linked to the TC. Apparently not! It's worse now because between the shift kit and the euro TC there is very positive engagement. So what now? I didn't replace the pump when I had the trans out but did all the filters, the shift kit and the new TC. The fluid was clear and but had a very small amount of black particles in it when I drained it prior to dropping the trans. I mean barely a noticeable amount. I really don't know where to go next. Any ideas would be helpful. I don't have a ton of experience working on the insides of an auto trans. |

This is a difficult thing to diagnose, mine was doing the same thing last year and the dealer couldn't figure it out. I am sorry to say that a complete rebuild was what fixed it for a time and then it was reworked on and finally replaced with a remanufactured one about a month ago. You have to be pretty knowledgeable on transmissions to be able to rebuild one these correctly and the service manager at the dealership informed me that he doesn't like opening a transmission to replace parts.... he would rather install a remanufactured one (let the experts do it) or buy a good used one. He said that when a TC begins to fail, it will continually disperse metal shavings and other foreign objects throughout the transmission via the fluid, all the parts will need to be removed and cleaned. He said it is never the same again. It's an expensive ordeal. |
