I knew it was on its way out but yesterday my transmission finally decided it had enough of this life. I managed to limp home from work yesterday afternoon and the diagnosis so far is a busted torque converter and worn clutches. We're thinking it could also be the trans oil pump but we won't know for sure until we pull it out.
I'm thinking the mighty stroker gave it more than it could handle. It's the 32rh 3 speed auto. I had relocated the breather, put a deeper sump on and also run an external trans oil cooler. A shame it had to go but now i'm looking forward to trying something else in there.
With the 4.66L, at 100km/h it's sitting at about 3000rpm. Combine that with a fat exhaust the cabin noise is deafening and fatiguing to say the least (as much as i love the sound!). An overdrive now would be lovely.
I've been looking at swapping in an another Chrysler automatic (it'll be a cold day in hell when i put a Chevy part in my Jeep) so i've been looking at a donor tranny from another Jeep.
I'm not asking "how do i do this" but rather asking for general feedback, opinions and advice on selection. The points to consider are; I need it to be strong enough to handle the massive torque with the stroker (apparently the R in 32RH means it is only good for 200-300ft-lb?) and also give me an overdrive (I need it for touring!).
I'm completely unsure of the whole computer controlled set up with these transmissions so i'm not sure what would and wouldn't work with my 2001 TJ.
The 32RH is a hydraulic unit but the four speeds all seem to be electronic (i guess that means computer controlled?) I've been looking at the 42RLE which is found in 03-06 TJ's and 06-10 JK's but if they're computer controlled i don't know if it will work with the computer in my TJ. Also i don't know how these transmissions have been received by the people who use them.
Big thanks to anyone who can provide me with some helpful info.
