Believe me, I was a diehard Transgo recommender too but after talking with alot of guys who build auto tranny's to hold up to major power, they tell me the kits are not worth the hassle they cause. |
As you might know the late transmissions today are designed to be light weight for better fuel ecom not high performance --- well that in it self should tell you they are not good platforms for real power --- the alloy case powerglide of 1962 is and never was designed to handle 1000 plus HP but it does --- the overdrive stuff is for the most part all pop press or stamped steel hubs and drums -- TIN CANS ) -- ( not the machined steel hubs in the units of years ago ) failure in the overdrive units can almost always be attributed to clutch slippage from to much heat - sprag breakage -- gear failure -- and the alloy fluid pump stator support giving way -- as i know it -- none of those things were and are caused buy the spring kits and plate for the valve body trans go and others supply with their kits --- but theirs always someone who knows someone who knows that --- well you get the idea --- GM tried with their transmisssion group to use one of their units and it did not work so now allison is the trans of choice in the high powered trucks we have --- the later units like in the vetts are better but its real pricy to fix 3Gs and up --just my take --- jz
