Converting to an Automatic

I'm planning to convert my 84 CJ7 w/304 to an automatic. Will a 727 from a Grand Waggie bolt in? I plan to use a B&M cable shifter.

Re: Converting to an Automatic

You'll need a few inches of suspension lift for your front driveshaft to clear the tranny pan. you'll also need lots of other things, like a tranny fluid cooler, kickdown linkage, wiring, etc. You'll need a new brake pedal assembly if you want to get rid of the clutch pedal. You'll need a new starter solenoid for an auto if you want to use the neutral safety switch.

Re: Converting to an Automatic

The waggy version of the 727 should just bolt in. The Chrysler versions have a different bolt pattern.
The front drive shaft clearance is a problem without a lift.
When you find a waggy with a 727 try and take as many thing off it as you can.
There is a short wiring harness that connect to the 727 and the transfer case. It plugs into the main harness in the engine compartment and should work with your CJ harness.
Take the throttle linkage as well, and don't run the tranny without the throttle linkage. The 360 linkage should work with the 304.
I took everything from the cherokee including the steering column which is 1.5 inchs longer then the CJ's but it should work. The rest of the shift linkage I will have to adapt.
The throttle linkage I took from the 360 is not the same as the one on the 258 so I'm still looking from one of those.
Take the cover plates for the torque converter as well.
Also, make sure you get the right flex plate, buy a new one, <$50. I'm not sure if the 360 and 304 use the same flex plate, but I believe they are both "weighted".
You will also need the shorter flywheel bolts and the backing ring.

Here are a few tranny related links.
