So I finally completed rebuilding my 32RH or A904 transmission. My TJ is back to life, runs and shifts smoothly during my 10 mile test drive. Big thanks to the youtube videos of
@hear which gave me a lot of confidence to tackle the job. He was very responsive to all my questions.
Issues found after the teardown and parts replaced:
1. The front and rear clutch discs were burned. The rebuild kit from Oregon Performance Transmissions (OPT) includes new discs.
2. Dustshield plate (covers the bellhousing) was bent on top causing the torque converter bolts rub against it, making all that grating noise. I couldn't find a new one so I got one from Ebay for $28 in excellent condition. Had to remove the flexplate to get the old dustshield out. I wanted to replace the flexplate too but the one I got from RockAuto made by Pioneer won't fit (holes for the torque converter bolts don't lign up). So I decided to put the old flexplate back which seems to be still in great condition. Bought new torque converter bolts from Global Transmission Parts.
3. Front and rear bands are worn out. Not that bad but enough to make me replace them, lol. The OPT kit only includes the front band. I got the rear band from Amazon

4. One of the plastic spring guide for the shuttle valve was broken. Unfortunately no transmission shops or stores sell this part. Luckily, I found a used valve body on Ebay for $95, took the part I needed.
5. The rebuild kit did not come with teflon ring seals for the accumulator piston. I did not want to reuse the old ones because it wasn't sealing anymore, pretty lose. So I bought the Sonnax accumulator piston from Ebay (Sonnax 22841-04K) and it works great.
6. The pump bushing looked like still in good shape but since the rebuild kit came with a new bushing, I decided to just replace the old one.
7. The rebuild kit doesn't come with output shaft seal so I had to get one from Autozone.
8. I also replaced the torque converter remanufactured by TC Remanufacturing. RockAuto and Autozone sells it. I got it from Autozone since I have a 20% discount coupon (

9. The solenoid looked like still in good condition too but I just replaced it with a new Mopar brand I got from RockAuto.
10. The rebuild kit comes with all the other ring seals, gaskets and orings needed for the rebuild.
11. I also replaced the dipstick tube seal with Mopar brand from Ebay.
12. Used a lot of brake cleaner and air compressor to clean all the parts and housing.
13. Used a whole can of Kooler Kleen to flush both transmission cooler lines. One can is more than enough.
Thank you for everyone's input. Wishing everyone a Merry Christmas and a prosperous New Year.
