Which tranny is best for 350 ? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I got c1500 91' 350 4x2 , it has 700r4 and it's completely worn out, and I'm confused about which tranny best for cruzing and rough daily drive.?

Some suggested th350 and 4l60e ..

Have what you now own rebuilt. The later 700's were a lot tougher than the earlier ones and most of the performance parts for the '60E will fit. The '60E won't work without a controller.

If you can find one, a 200-4R is tough when built. They're not easy to find, though.

There's something wrong if you went through 3 rebuilds. The rebuilder isn't doing something right, the cooler isn't working properly, the TV cable is adjusted properly, or the truck is being abused.

There is nothing wrong with a later 700r4.

There are 4L60E's living behind 600hp LS engines on the street, parts are available to make 'em live. Next step is a 4L80E, it'll take everything you can throw at it but needs an electronic controller.
I'm not a tranny guy, but I know that there's a trick with the 3-4 clutch pack that seems to help on the 700/60E's.

Guys, consider where he lives. They don't rebuild 700R4's over there very often compared to America I'd assume.
My suggestion is to buy a built 700R4 from a well known builder in the US and have it shipped over. Make sure you run a transmission cooler as big as you can fit.

I bought another 700r4 that was in 93 caprice , i hope it will last for long .
