Woo hoo!!!!! Fully built Super Duty 4l60e= TOAST

Just to show how bad the 4l60e sucks, my $2400 built 4l60e just took a crap on me. Made to hold 600 hp my ass!!!!! It didn't quite make it a year, but oh well.....I knew it was a POS anyways. Now on to a better tranny. Probably either a TH400 or a 4l80e. TH400 has the price advantage, 4l80e has the overall internal bulk advantage. Both would suit my racing needs, but the damn 4l80e vaps so much hp. We'll see which way to go when I decide to get to work.

Just another post on the crap gm puts behind their motors. Looks like the TCI converter might have come to pieces causing the tranny to fudge up. Either way they both SUCK!!!! :lol:

That pretty much sucks man. I've always hated GM trannys. Why do't you put a c6 in there? lol j/k

If I had one laying around I would sure the hell try. Bolt it up to a Ford 9 incher and not have to worry about either. :grinyes:

I have one of each just kinda laying around. I think the rearend has been narrowed though...maybe not. It wouldn't bolt up in place of my old 8.8.

or try a T56 conversion....:naughty:

What's the estimated power loss on the TH400 vs 4L80E?
