I just bought this 2001 p71 which went from cop car to taxi. (ugh I know I shoulda just bought it from the cop auction) Live and learn........
From a stopped position it will frequently seem to shudder or slip a bit. This happens more frequently and more severely when the car has been driven a bit. I had someone drop the pan and replace the gasket and 4 quarts of fluid. (I'm not really very skilled mechanically, but getting better) I now read that this only changes out a portion of the fluid and it would have been better to flush the system. It has over 222K miles on it. When we did this original change the shudder went away but soon after returned. I'm suspect that it should be flushed out completely. I'm curious if this is just a fluid issue or if the trans should be replaced. I found a trans in a junkyard with 80k on it for 400.00 and a trans shop to do the pull and replace for 300.00 same day.
I'm I headed in the right direction to correct this issue or am I going about it all wrong.
Thanks in advance for any information you may be able to offer.
