and don't want to break down on a trip. What is the best way to go to get the best rebuild and performance ?
I rebuild these transmission for performance applications mainly but still do stock rebuilds. Anyway's in my opinion I don't recommend shift kits, most shift kits will give the vehicle taller shifts. What I prefer to do instead is to modify the stock valve body seperator plate. I from experience don't like transgo plates, they aren't made of a high quality in my opinion, the plates are stamped and the holes and cut outs have a very sharp edge that would need to be smoothed out. Their are modifications that can be done to the stock plate to increase lube flow to the clutches and prevent binding.
In terms of performance as for parts I really have a unusual combination but it works, well!
I use only Alto Red's and Alto's Kolene Plates. Now where the combination comes in, I use stock replacement Borg Warner kickdown band and a Raybestos Hi-Energy Rear band. The reason for this setup is because I tow also, and if I ever have to manually downshift to 1st gear I have a very resilent band that grips tight on drum but doesn't score the surface.
I use a stock flex band because this band is used everytime you're in 2nd gear so if I used a hi-energy band or a kevlar or carbon band then I would ware the direct drum very quick, bands are cheaper then drums!
I also prefer using a 6 pinion rear planet, they're cheap and have many benefits.
Another thing I do is remove the anti-drain back valve and place a external cooler where the valve would be, the primary reason for doing this is to cool the transmission fluid before it enters the stock cooler in the radiator. In severe use the transmission fluid can get hot enough to actually heat the engine coolant enough to overheat the engine. The external cooler also serves as a anti-drain back valve.
