got in the car today, cars flaring gears like crazy, time for a new trans

Ive been looking at the bowtie overdrive level 3 4l60s, they look like theyre the ones.

i want the inputs on what you guys have done or would do....!
AND NO COMMENTS ON CONVERTING TO 6 SPEED!

why not just move on up to a 4L80?

cause the 4l80 requires too many modifications to install, like hacking the lower firewall, cause the trannys much bigger than the 4l60

Nope 4l80 has more incommon with the th400 internally than the 4l60 aswell..:thumbup:

a built 4l65 is cool, well, its only the 5 pinion planetarys that are different, was looking at them too. the turbo 400 is a monster but id lose overdrive. i think the best bet is a built 4l60

You sticking with the 4L60E or you wanna try a th400?

I think performabuilt does a nice job on transmissions, a lot of people choose their tranny. They should be a sponsor on here.

yeah. performabuilt is a sponsor on here.

how about a 700R? its similar in build to a TH400...but its geared a little lower, and has overdrive, the TH400 doesnt

except the fact of the electronics difference...4l60 and 700r4 are similar

I dont know about that I've had v6's that where stock that the 700r4 could'nt hold the abuse. I've also had a 74 4bolt 350 that was out of a wrecker that ate my 700r4, but once I bolted a th400 up to it could pull the hatch off a submarine.. The only simularity I saw was they both bolted up to the 350 v8..:yup:

Yeah just have one built to take the abuse and you're proly golden..:slash:

getting one built for what you need is alway's a good idea...
