I really wouldnt focus too much on the VSS unless you have a code for it,... its driveability issues are not by any means minimal and both times it produced a specific code indicating its failure. If indeed you DO find a code present for the VSS, ALONG w/ the driveability issues, it needs to be replaced soon and immediately or you will wreck your trans fast and permenantly because of the slamming and slipping it produces. Because of its significant labor I wouldnt just throw the part at it. As far as a new CPU goes I have 150,000 on my origional trans and "weak" CPU, but it still holds it own, but I rarely beat on my "old" car anymore. IMO A new CPU is is of little help to a 13 year old trans. with high mileage. If you want those crisp shift points just adding a 94 isnt going to do much but give you a false sense of security about the aging trannys strength and may cause you to push it past its abilities. Absolutely no offense intended, if you want to race your sho then you really should look into a modified rebuilt....quaife!. If thats what youre looking for it would financially be more intelligent to start w/ a MTX...You can probably find one cheaper than a rebuilt trans and they are faster, easier to work on, and the handle the road much tighter than an ATX. Ive had both but had to move and had too much money invested in the ATX to give it away which was unfortunate because the MTX was a killer and rarely gave me the problems the atx has.
Good Luck either way, my ATX is mostly a grocery getter nowadays, but its still nice to have the potential!
