Alright 1995 Sable Vulcan engine, AX4N trans.cable driven speedo. 100K miles
History: Always a hard 1-2 shift. started to downshift into first while driving and was hard to get to upshift. Replaced filter and added Sea Foam Trans Tune. First test drive the symptom was still present so I parked the car.
3 months go by I take it to the trans shop, but, as always when you take a car to the shop the symptoms go away. OK so I assume that what I did helped but I didn't drive it enough. I drive it about 1500 miles with no problems then it happened again. After a drive of about 130 miles and a couple of stops it downshifted and wouldn't upshift unless I coasted for a while.
Within the last three days: Added Lube Guard Red, no help. Replaced VSS and then things are well..different now. It will now not upshift until about 25-30 MPH on light residential street cruising, seems to be revving too high in first at cruise. So late upshift from 1 to 2. 1-2 shift smooth but now 2-3 shift hard. When I took it on the freeway it would go into OD but it seemed a little hard for it to go into OD and the one that bothers me a lot is it wont downshift on Accel eben when it's in OD I can floor it and it stays in OD, this was done at 55MPH+ up to about 80MPH.
Since installing the new VSS I have put maybe 20-30 miles on it. Is this part of the relearning?? Or is tranny crap?
Please help! This thing is driving me crazy.
Thanks!!
