Really depends how you drive it. Not sure how many miles it has but with performance mods the tranny is on borrowed time.

tune your afc correctly and you'll save on the trans abunch too if you have a tendancy to horse the throttle around. it delays full power for afew seconds; but once your rolling it isnt near as much strain as a dead stop at WOT

put a good valve body and converter, and input shaft and flexplate in the tranny she will hold up alot better. also look into the torque converter lock up switch as a search on here its another cheap and easy mod that makes a big diffrence

thanks guys
