So I picked up a CTSV T56 today, special ordered with the tri-flange setup. I would like to insall this tranny in my 1991 Silverado which doesn't have the tri flange setup. What is the best way to go about changing it/adapting it?

How it looks..


How I want it to be...


Any help is appreciated.

And read the pdf in that thread.

If the shifter location is good for you, keeping it as-is might be a good option.

The shifter location is perfect, its exactly what I needed. But I'm not sure if I'm confused, or your confused but I need to figure out how to hook up to my driveshaft that I have now using the triple flange.

Whether someone knows where to purchase an adapter maybe even?

Driveshaftshop.com can make you a driveshaft that will work with the flange so that you don't have to convert the trans to a slip yoke. They do away with the U-Joint and slip yoke and use a CV that bolts up to the flange with an adapter. The CV allows the driveshaft to move in and out with rear axle travel. It will use a U-joint to connect to rear end.

A CV driveshaft won't have the travel that he will need in a truck.

This is what I ended up doing, its a 1330 U-Joint, anyone know how strong they are? Still need to measure out what driveshaft length I need.

Where did you find that? I've got the same trans facing the same issue. Thanks

Rick1991

I took it to a local transmission shop and they had the ujoint. Its supposingly off a ford.

I just wonder since it's fixed in place how well it'll hold up. Seems like there should be some give line a slip joint setup.

I haven't even started the swap yet so I couldn't tell you. The driveshaft will have some give in it when I get it made.

Make sure the yoke fits properly against the output shaft seal. I know a guy who burned up a perfectly good 5th ten Camaro unit trying to do the same thing as you are. He put a yoke on there that didn't fit the seal properly and it leaked all the oil out and burned it up.

Wow thanks for the warning, I would be beside myself if that happened. Alberta driveline is working with my so I'm trusting the "professionals" know what they're doing.
