Manual to Auto tranny swap

Greetings,

I currently have a 1987 Wrangler, 4.0, 5 speed poo-geot. I'd like to convert it to auto from a same year wrangler. Are there any things that I need to be concerned about, or is it just a bolt the tranny on and go application?

Thanks

make sure you get every part of the linkage. also make sure the trannys are the same length unless you can get the driveshafts with the new tranny or you wanna buy new ones($$$$$)
personally, i like a column shifter, but a floor shifter is a lot easier to install..especially since you allready have a hole in the floor

Re: Manual to Auto tranny swap

Super,, I happen to be doing just what you are thinking about. I too own an 87 and converting to an auto. The Tranny that I am using is out of an 86 CJ, the 904. The tranny length is just 1/2" longer than the Peugeot tranny and will bolt right to the I-6 engine. First do you have the NP231 or the NP207 x-case?
The NP231 x-case will bolt right to the 904 with a few changes, ie; you will have to change the input gear on the x-case to the 23 splines that are on the output shaft of the 904. Be sure to get the LONG gear for the auto's the SHORT gear is for the standards. Other things you will need are as follows.
auto tranny mount and torque bar
flex plate and bolts, both crank and torque converter bolts
kick down linkage for I-6
X-case shift lever and linkage
(auto is diff. from standard)
shifter for tranny (I bought the Z Gate shifter from B&M $119.00)
auto brake pedal assembly (I wanted a complete change over, this is not needed)

You have the Ford type starter in your 87 and this will bolt right to the 904 bell housing. Feel free to e-mail me with any questions at [email protected]

I also opted to put the slip yoke eliminator on my x-case at the same time.
