One of the changes I wanted to make was switching to a auto trans. the most recent wife
has trouble using a clutch, she broke her lower leg and had a rod in it until about a month ago.... (long story it has been a bad year for her)
I was tired of shifting and wanted to go back to a auto....having her able to drive is a benefit in so many ways, so that was the first thing I swapped.
My 4.0 with 1 tons and 4d's was... is a turd. Only used overdrive down hill. My Jeep is a 2005 so trans swaps is very limited, CPS was a real problem, jeep changed the sensor signal on 05 and 06
So after a bunch of research the best choice for ME was 32rh. bolted right in.... no adapters need for motor or transfer case. I moved the CPS to the harmonic balancer,
I had Mike of Mikes Transmission in Lancaster CA rebuild it, I knew mike from drag racing days and his trans kick ass. It's pretty much a street and strip deal with some changes better suited for off road.
Here it is ready to install...you can see the moved air vent on top of the trans, I cleaned up the atlas, new gaskets and added flanges. I always had a oil puking problem out the vent...so I moved the vent. plugged off the stock one and ordered some fitting to redo the site tube, not sure if it will work but it has to be better, you can see how I added the fittings in the pic.
First gear: 2.74 Second gear: 1.54 Third gear: 1.00 add that to a 4.3 low atlas = 11.78 x 5:38 R/P =
63.5 low range auto ! :nuts: I don't know if others drive like this ...but I like to have really low gears so I can drive through technical stuff by just riding the brakes, buy using brake pressure to modulate the speed and not having to worry about stalling. I think that's common, just hate to keep my foot on the gas all the time, when the trail speeds up you can pull your feet off... it's nice to relax the feet as you drive...I have feet problems from my job.
Here is the CPS I moved to the balancer...
Also added a tranny cooler next to the power steering cooler.
