Welp, i think my 3rd 4L60E is starting to slip again. I would do a turbo tranny swap, but I want it to retain the overdrive gear, cuase I tend to do quite a few highway runs....are there any trannies that won't **** over after 6 months that do have a 4th gear? It will be sprayed, and prolly cammed, so I need a beefy tranny. Any help is appreciated!!!

Do a 400 with a gear vendors overdrive. If you would have done that from the get go you would still have a strong tranny and paid WAY less than 3 4L60E's.

But hindsight is 20-20

Or you could do a 200-4r trans (I have one for sale if you are interested, not trying to be a salesman though). The good 200-4r's came out of the grand nationals with the BRF valvebodies. One similar to mine (Same internals) is powering the TSP race car.

 

I'm doing a 4L80e now but it has been no easy project so far. It will cost around 4k by the time I finish this, but it is better than pulling the tranny out every month. That gets old really fast. The th400 would probably be the easiest swap with a gear vendors od unit.

 

Liberty transmissions n Texas. They r building 4l60e strong enough to live n the 9s. If u blow that up with the little mods u have now. then u must have something ur not telling us about
