New Tranny

Well, I didnt really want to buy a new transmission, but mine seems to be slipping and actin' a fool. So, I'm looking at getting a new one or having my rebuilt. I have a 2000, auto 2.5l, so it has the 3 speed 30rh transmission correct?

I'm looking to stay as low in the price as I can, I can install the tranny and anything else, but can't rebuild one. Just wondering if I should just pick up a newer 30rh, rebuild mine, or maybe think about doing a swap to something better. I wish this money could be going to the lift and bumper and corners I want!!

I'd really like to have someone that isnt a tech at the dealer take it for a spin to see if whats going on in there is normal or something wearing out. Its got 140000 on it, but I don't know what a good Jeep tranny should feel like. It just feels like 1st is kinda short, but then going into 2nd gear especially cold, it slips and itll rev up to about 2000 if im on the gas still and then itll engage into gear. Then going into 3rd gear its fine. Just 2nd gear with the way itll seem to slip worries me.

Any Ideas?

Personally I'd just go find a used 30RH (yes, that is what yours is) and install it.

No one accidentally used the wrong ATF in yours did they? The only ATF suitable for a Wrangler automatic transmission, 30RH, 32RH, or 42RLE0, is ATF+3 or ATF+4.

Thanks for the quick reply Jerry, if I didn't get a reply I was gonna PM you cause I know you did a 30RH swap. When I serviced the transmission I used ATF +4. And its filled to spec and it reads fine when cold and warm. So it looks like im gonna be looking for a 30RH!

Did you get a Jeep unit? or did you go with a unit from a different vehicle and use adapters?

I didn't do a 30RH swap, I swapped in a 32RH. Close enough though.

Ah, gotcha. Would a 32RH be a better alternative? I would need adapters im sure.

The 32RH has a completely different mounting bolt pattern, the 30RH is fine for the 2.5L.

Thats good to hear! I'm looking at all possible swaps, I'd like to go for a beefier transmission, but looking to save as much money as possibly. I'm also going to call a guy I know who will rebuild it brand new and see what he charges.. How much did you pay for your 32RH?

Mine was $800 but that included nearly everything needed to convert my 5-speed to the 32RH... shifter, transmission, cables, nuts and bolts, torque converter, flex plate, etc. and even a new radiator that I didn't really need since all OE radiators are ready for an automatic.

Hmm, i'm going to do some good research and see whats the best option for durability, price, and time as this is my DD.

I was thinking most swaps or rebuild would be around the $800 dollar price range, so I'm gonna try and stay around there. I'd love to go to the 32RH as its more HD. Gonna look up some build threads as I'm already auto, did you have any problems ECM wise? I'm sure since yours wasnt controlled before it doesnt need to now, I know the RH in the word means its hydraulic controlled not computer or electric.

Again, the 32RH won't fit the 2.5L. Way different bolt pattern. I changed my ecm out to one programmed to control the auto transmission's torque converter lock-up circuit.

I read your first post wrong Ha! But thanks for the info Jerry. I just like looking ahead to the best bang for my buck once this becomes my trail rig only in the next year or two. But with more transmission, comes the need for more motor haha.

I appreciate all the help, I'm gonna outweigh my options and pull the trigger. I could get some nice aluminum armor or tummy tuck with this... oh well, neither of those will get me down the road

Have the exact same symptoms in my '97 2.5L. I think a rebuild might be in the future. How much should a rebuild cost?
