I have an 89 mild built foxbody. (306 forged internals cam gt40 heads roller rockers nitrous kit long tube headers and a few more goodies). I was wondering what is the best trans to put in place of the t5? My second gear is starting to pop out every now and then and instead of rebuilding it I’m thinking on just swapping to a better trans.

Tremec has stopped building the TKO transmission.. If you want to buy a new TKO, you need to buy from what stock is left.... The TKX is replacing it...

Apparently my ex-husband made that mistake.

A T5 in good shape is fine as long as you aren't putting sticky tires on it.
