Okay so I I have a 1994 SHOwith 126,000 miles on it, the 94 tranny went out on me so I replaced it with one out of a 93 that is supposly rebuilt. Well the tranny shifts 1-2-3-4 Just fine but it does it really fast. Doesnt kick-down, If you give it wide open throttle it wont downshift and take off. I can drop it into second gear remember this is an ATX at about 50MPH and match the tach with the speed so it dont hurt it and it goes like ****. The car wont get up into the secondaries even. I replaced the speed sensor and it still has the same issue. I also sometimes have to shift the car to nuetral then back to park and back to nuetral in order to even start the car. It threw me a VSS problem. Is their a difference between the 93 VSS"s and the 94 VSS's. could th estarting problem be a nuetral safetey switch as well as the shifting problems??
