Default 98 5.2 to 01 5.9 tranny swap?

just got a 01 ram 3/4ton gas cheap because of a tranny issue. I have a 98 1/2ton 5.2 with a blown motor. I thought i could just swap'em out considering there both the 46re, but after looking into it i came across a few people talking about wiring differences over the years and something about the transfer case not being interchangeable between the 5.2 and 5.9? the transfer case in the 3/4ton works just fine, so i was wondering if i can put the 5.2 tranny(without transfer case) in the 3/4ton 360?

Transmissions will swap just fine. Only problem you will have is the electronics in the trans. The pressure sensor returns a different signal than what the newer PCM will expect. Easily fixed by updating the electronics in the trans, and using the correct retainer.

Yeah, just drop the pan, replace what's in there. You can get the retainer from your current trans, and transfer it to the donor trans, along with NEW governor pressure sensor/solenoid. Do not use the old ones..... might be inviting trouble you don't need. The retainer is for the sensor, I think... They way it mounted changed..... there may also be a difference in the internal connector for the o/d and tcc solenoids.... It really wouldn't be a bad idea to simply do ALL of them, while you have it open. There are kits available on Ebay for around 200 bucks..... comes with the borg warner heavy duty governor solenoid......

Something like this? i watched a video on replacing the governor pressure solenoid and transducer. Didnt look hard.He pointed out the overdrive and lock up solenoids, but didnt take them off. didnt look like alot of extra work though. and i seen the difference in the retainer. anything else i should keep in mind?

Just realized the coneconnens don't match up to the old wiring, anyway to do it without dropping the valve body? Only one don't match up. Old

Yeah, you need to swap the O/D, and TCC solenoids as well. You *might* be able to do it without dropping the valve body, I recall someone mentioning it was possible, just difficult.

Yeah, I got the kit you was talking about. Od, TCC and pressure solenoid's all match up, it's just the transducer with the different connection. To be honest they both have the same 4 wires and color codes, I thought about splicing them. But I'm not sure how good that'll be with the splice sitting in tranny fluid! But I'll look around a bit, see if I can't find something.

The pressure sensors are different. You MUST use the correct one for your year truck, else the PCM will get wrong pressure and temp readings, and you will be in there again.

You need the retainer for the governor solenoid, or the pressure sensor, out of the 01 trans as well.... (don't recall which) else it won't seat right, and you will have problems.
