    A stock 80e will outlast a fully built 60e and they are cheaper also.

    change xmember, rewire the transmission connector and swap to a TH400 yoke. You'll also need a new tune setup with the 80e programming.

    You can buy a crossmember for a 80e swap, or just get someone to cut more the center of the crossmember about six inches i think. then weld it with 1/4 metal extensions.

    i dont remember what site but someone does makes an adapter to switch from 60e to 80e, or save the money and do it

    If you want your truck to shift like a tractor then go for it.

    No. Just stick with the 80e swap. You'll be glad you did it.

    First off. Many have done the swap and their times have gotten better because of the ratios. Second off, even if the 80es had electrical problems think off ALL the problems a 60e has

    60e = Junk
    80e = Reliability and Strength
