So with two rebuilds on my 46RE (2000, 2500 gasser)- first at 130k and now worn out at 330k (nothing to complain about there!), I want to replace it with a Jasper remanufactured one.
Taking it to the shop tomorrow for a look-over and labor estimate, anyone here had it done? Wondering what a reasonable cost would be for this...
I know there may be other incidentals required by Jasper (maybe a new cooler) for warranty.

 

Mine was a 46RH and the first one cost me $550 in labor. The first one vibrated really bad and was replaced but not really, he said he replaced it but didn't. Had to bring it to a different repair shop to really have it replaced and they charged me $750. Jasper covered $550 to warranty it.

 

2 or 4 wheel drive? I think R+R trans is right about 6 to 8 hours according to the book... so, multiply by whatever the current labor rate at the shop is.

 

Thank you!

 

So a strange (to me, anyway) update on this.
Jasper-approved shop was busy, took a week for them to get it on the lift to get the info they said they needed off the tranny and the requirements from Jasper.
It was delivered yesterday, but before doing the swap today apparently one (or maybe more) of the mechanics thought that the slipping, rough shifting, etc might have been due to a clogged cat converter.
Removed the converter, took the truck for a test drive and they tell me the engine and transmission ran and shifted perfectly. Trans hadn't been touched and was still palletized so easy enough to ship back.

I've never heard of a clogged cat causing these issues? On the one hand, I suppose it's good news that it's a sub $1k repair instead of near $5k (although with 330k total on it I wonder when it will be toast, despite an easy life). Didn't get any codes for the O2 sensors, he said on a truck that old, might not throw codes for this?

Aside from rough shifting.and slippage, it wouldn't run past 50 mph on the interstate- I'd press on the gas, and the engine didn't increase rpm. It was total lack of power. Could that have been due to backpressure?

I'm gonna run the shiznit out of the truck with the new cat after it's installed, but told them not to send the trans back to Jasper- yet.

 

Clogged cat would indeed give you the no power problem, but, shifting issues??? No clue how that would work.

 

Well, I guess this makes sense...

When the catalytic converter is clogged, it creates a bottleneck in the exhaust system. This traps exhaust gases in the engine, making it harder to breathe and killing power. Since the transmission is programmed to shift based on engine load and throttle input, this reduced power confuses the system and can lead to hard shifts, slipping, or incorrect gear changes.

 

That does make sense...... Some of the sensor readings would get rather odd..... and the PCM really isn't all that smart.
