Rebuilding a 1983 CJ8 Scrambler

[Eugene]

Hello all...
I have two CJ rebuild/restore projects in the works... I know. Lost my mind, but the second is a CJ8 Scrambler. Same make and model as my first Jeep... ever; I couldn't resist.

My quick question is this; will a 3sp Auto (32rh) Transmission from a AMC 258 i6 / 4.2l I-6 (YJ) bolt up to the original CJ AMC 258 i6 / 4.2l I-6 in the Scrambler?

I appreciate all input, feedback and any lessons of wisdom you can offer me... yes, I'm a newb at the rebuilding.

The AMC 258 i6 / 4.2l Yj is basically a AMC 258 i6 / 4.2l Cj. The Transmission will bolt right up. What Im not sure of is if the Dana 300 will. I thought the Yj actually used the TF999 ? Im not really up on Yjs though.

yeah as far as I know the TF999 was the yj auto behind the 6 cylinder but it should bolt to your engine..I think the 32 was used in 97-02 tj's behind the 4 cylinder as well as the 4.0

The YJ's (88 and up) use the NP231 Transfer Case , so while the later Transmission will bolt to the motor, I don't believe your Dana 300 will bolt to the Transmission without an adapter. Best to call someone like Novak about what you want to accomplish.

I'm pretty sure the YJ used the TF999 , especially if it's a AMC 258 i6 / 4.2l YJ.......

yep..87-90 AMC 258 i6 / 4.2l & 91-95 4.0

Ive just done a ton of reading on the NP231 and the ones that came behind the autos had a 21 spline input shaft. How does that mater to you you ask?? your Dana 300 has a 23 spine input. Thus the Dana 300 would not fit unless you either change the output on the Transmission or input on the Transfer Case .

Good luck.
