Im saying beat the **** out of it!!! ....lol ... you said you have a weak tranny you cant get the shift pressures right ? i bet a $beer you wont/cant kill it cooler addition or not.

Beating on it means so much to so many people,I have seen posters kill a 4l60e in a almost new bone 2x4 stock 4.8 truck,somehow they destroy the trans,more than just one.... we/I have seen guys with 5.3 turbo 500 HP 140k miles and 4L60E vette servo trailblazer converter trans still living
Beating on it means opinions vary

 

It def should be good to go after the upgrades and converter.... I hope! LOL

If not.... pull it and build it better next time

 

****.... I'm gonna give it all that I have the first go around. LOL

Sadly when i build a trans or an engine, the initial test drive will either break it or its going to stay together... Probably the hardest 12 miles they will ever see, unless its a tahoe or caprice ppv!! I put them through two drive cycles driving normally enough to set any codes then i will make sure i hit every possible condition the car could see!!! Very rarley do i have any come back!!

 

have you pulled out the tranny thermostat in the cooler line block near the trans case. that should cool her down problem solved

 

Any more info on this as I want mine to be a bit cooler also.

 

Yes, get with OP. in another thread he mentioned using a tstat block in place of tstat and has had no issues. I think he said trans temps run in the 160's all the time now. I dont remember all the details

 

My 6l80 reached 210 on one occasion towing at altitude(highest point of the tow really) have driven 10k since that time, all seems to be fine. I wonder where the max safe temp is on these? 225 maybe?

 

Im good with leaving mine the way GM engineered it
