MiniTransAm Posted October 30, 2006 Share Posted October 30, 2006 Howdy We've had this car for over a year now. The transmission has done this since we owned it. When shifting from 2nd into 3rd, you hear a very audible click or a clunk noise (depending on how it's feeling that day) and the car will lurch forward. I have also noticed that it's a bit slow (I think) to downshift into 1st gear when coming to a stop. We also get a weird "rattle" noise when in OD when you give it just a bit of gas. Most noticeable when going up a slight hill and you don't need to give it enough gas to make it downshift. The shift from 2nd to 3rd also takes longer when it's cold. It waits longer to shift than when the car is warmed up. I have drained and filled the tranny twice already when we first got the car. It's probably about 70% Synthetic and 30% dino. Could this be a sticky solenoid and running some sea foam through it and changing the oil again would do the trick? Quote Link to comment Share on other sites More sharing options...
teppichkopf Posted October 30, 2006 Share Posted October 30, 2006 What kind of mileage on the tranny? Service records from previous owner(s)? From experience with two auto trans that had similar problems, once they're bad, they're bad. I tried flushes and no slip products but nothing took care of the hard shifting. Usually of neglect from previous owners. Quote Link to comment Share on other sites More sharing options...
MiniTransAm Posted October 31, 2006 Author Share Posted October 31, 2006 114K or so on it. Don't really have much on the service history. Looks like the previous owner did the basic maintenance but that's it. Timing belt was chagned. I don't remember seeing much about tranny maint.

nipper Posted November 1, 2006 Share Posted November 1, 2006 I think the cause may be some mechanical damage inside the tranny. These are hard shifting but well behaved transmissions. LOnger shifts when cold is normal. The rattle can be a heat sheild, but the clunk has me concerned. you may need to take it to a shop to have it diagnosed. nipper Quote Link to comment Share on other sites More sharing options...

I hate to do it but I may just drive it till it blows up. If it ever does. Perhaps a trip to a dealer in this case may be a better bet since they more than likely have seen a similar problem before.
