    Not without a whole lot of work. And why would you want to take several steps backwards? Just get your 4L60E built right.

    That would be a much better option than trying to retrofit a 30 year old design.

    A 30 year old design that lacks an overdrive or lock-up convertor.

    But, if you do, just pull all that stoopid emissions stuff out too. Drop in a good ole 350 with a 4bbl and give me your old crappy stuff. That way you don't ever have to worry about all that new electric stuff going bad again.


    Seriously though, have it rebuilt right or consider a 4L80.

    Re: 4l60e to a turbo 350

    i've had the same 4l60e for as long as I've owned the truck, 45,000 miles, i've towed with it, i have a very heavy foot at times, i've offroaded it.... and it works perfectly, and its nothing special. Something isn't right here...

    That's kinda what I was thinking.

    When I said "built" I meant by a good reputable tranny shop that builds specific to your application.

    Get a Raptor I am sure they can build you one that you can't tear out.

    I had my 91 Firebird and now my 91 Vette using a tranny from www.rosslertrans.com and they were recommended by Lingenfelter. I beat on that thing daily (several times a day too) for 3.5 years before breaking the sun shell gear. That was mated to a 440HP 383.

    Re: 4l60e to a turbo 350

    Going with a 350 means you won't have overdeive or a lock up converter. Your gas mailage will go down, your transmission temperature will go up and a stock TH350 isn't any stronger than a later model 4L60E. Of course you can get a TH350 cheaper than a 4L60E, and get a TH350 rebuilt cheaper also. But you will have to have yout computer re-programed (more $) so you don't get a code light on all the time. You will need an adapter so you can have a working speedometeer (more $) then you will have linkage problems, What are you going to do about kickdown for passing etc.

    To me its a lot more trouble for something that will not work as well. BTW you do have a 2WD truck right, If its a 4X4 it will be a lot more $$$$$$$
