Oddball 5-speed to T-case question

I have a wild hair that I'm not sure is even possible but would be super badass if it works. Do you guys know if a close-ratio 5-speed stick from say a Camaro can be adapted to join a transfer case for installation in a Jeep CJ-7?

All of the common transmission swaps use old truck sticks and shift like a school bus with a near useless granny 1st.

I'll ask my boss, but I do know the Jeep T5 has the granny gear for the 4-banger. These were factory adapted to the dana 300 T-case
You'd probably need the entire shifter and internal linkage from a jeep T5 to convert the camaro box to forward shift. Additionally, the camaro box is mounted tipped to one side 15* towards the driver, which means I doubt the mounting foot is correctly oriented for a traditional crossmember. Dont forget the early 80s 4L was torquey to kill the Jeep 4:1 1st NWC trans.

Ed Hartnett in Lansdowne PA did a lot of customized T5's; he may have some ideas. 610-623-9381 Tell him Nathan from Auto Gear sent you.

I wonder if trying to hang a t-case off the back of a Muncie 4-speed would be an easier deal :-k

Advance Adapters has a kit. Or they used to. We've built them for customers. Its a special mainshaft and tailhsg for the Muncie. We've almost always done them with our 2.98 1st gear on the rockcrusher platform.

The other road might be to get a Jeep T5, and put a factory replacement 2.95 camaro non-WC gearset in it. Let me know what Ed says.

I would use the case from a Jeep AX-15 transmission with the gears from the Toyota Supra version the R154 that came in the late 80's Supra Turbo's.

I have a new Advance Adaptors Muncie to Jeep transfer case conversion if interested.
On the T-5 that was a factory deal. If you want to lose the 4.05 low gear, 3.35 or 2.95 low gear sets can be swapped. Need to keep it world class or non world class depending on the tranny case you are using.

I saw a car show on TV a while back where they converted a late model Camaro to 4x4.

The kept the 5 speed and used a late model junkyard transfer case.

I forget the name of the show unfortunately, anyone else see it ??.

I just remembered "Road Hawks"??

Thanks
Randy

You *should* be able to swap to a Jeep or Eagle T-case adapter from the original tailshaft housing and use a 23 spline output shaft from the same application in order to mount up a Jeep T-case. If your box is a WC, then you'll need to modify the Jeep output shaft to work with the WC needle bearing where the output shaft plugs into to the input shaft.

Also, the Syclone/Typhoon/Bravada T-case works with GM's normal 27 spline output.
