if you are gunna put a heads and cam i then just go with an FLP stage 4. that is what im putting in my camaro. if you get it rebuilt then you might as well build the tranny up which will cost $2000 or so anyways.

if you go with a rebuilt you should be able to request they beef it up to make it stronger ,without adding to much $$$$

How did you determine it's slipping, seat of the pants or are you logging w/ something like HPT? When is it slipping? At every shift, only 1/2 or 2/3, only on downshift at cruising speed? If you're not scanning it you should try to find a way to. According to what it is you might be able to do a tune fix by upping line pressures, changing shift times, etc. If it's actual clutch slippage this isn't really a fix but if it's just slow soft mushy shifting it is a fix and can help decrease clutch abuse caused by slow apply.

If you do need a rebuild do yourself a favor and do it yourself. Buy upgraded parts (beast shell, ect) a rebuild kit (w/ good clutches/steels) and a manual specific to your year and go to it. You may need some tools you don't own (to compress springs, remove split rings, etc.) It will save you a ton of money and you can say you did it yourself. A hint if you've never done it before, set up two benches. One to lay parts on in the order removed as you tear it down and the other to assemble on.

To get some other ideas about what's involved go over to www.firebirdnation.com, register and then look at the tech articles. There's a very good one with close to step by step 4L60E rebuild instructions and pictures.

And yes I've done this myself. A few weeks ago I did a complete 4L60E rebuild. This was the first time I had seen the inside of a 4L60. Took it out and apart on a Saturday and rebuilt and installed on Sunday. Two full days of work but the way I figured it I was making about $80/$90 an hour

can a blown tranny be returned as a core?? Or do you have to return it before it's done?
