I managed to get hold of the previous owner who had changed the tranny filter/fluid etc when it was serviced before he sold it to me.He was supplied with all the correct partsfrom Dodge byquotingthe VIN. So I'm now 99% sure I have (as previously stated) a bog standard 46RE. The seal must have been fitted incorrectly or I was supplied with the wrong parts.
I will now order another seal and maybe a filter kit from my local Dodge dealership rather than the aftermarket parts supplier. The Dodge dealer does not sell Rams but they have told me they can source (from the US) any part I require, as long as they have my VIN.

 

Having looked through other OEM sites I've found out that the tranny filter kit which didn't fit is actually for a 4x4, so now I know why it was wrong. I'm sending it back for a refund and will keep the current one fitted as the previous owner only fitted it 4000 mls ago.
As for the seal:
According to the part numbers, the first seal I bought (which didn't fit) was indeed the correct seal for a 46RE (+42RH).
The seal which was then fitted (its now leaking) has a part number which matches a 46RH (+36RH).
I have read that a 46RH was not fitted to a 2000 Ram so I still am nowhere nearer knowing what I have.
Can I identify the difference between the RE and RH by just looking at it ???? (The stamp on the tranny case is for the 46RE)..

 

I haven't solved the leak yet but the parts supplier has now sent me this:




It is a sleeve that fits over the shaft. Could this be my problem or am I being sold something for the sake of being sold something ?
Andanother thing, can you tell the difference between a 46RE and 46RH by just looking at it whilst lying under the truck?

I park the truck on my driveway which is on a slope. The front of the truck points uphill. It has been stood for over a week so I fired it up today and drove forward and off the drive. The front of the truck is now facing downhill, so I get out and look under the truck to see tranny fluid pouring out from underneath. This continues for 15 seconds and then begins to stop.
I can only think that whenI've been for a drive ,the fluid leaks as its being circulated and any excess still leaks out when I switch off. Once the fluid has cooled and settled is it possible that the fluid is still leaking, but rather than dripping out is actually being caught (as I park on a slope)somewhere else under the tranny and as I start to drive it levels and pours out from the nearest hole?
Any help appreciated as its going backto the mechanic next week. Thanks.

 

Thats a "speedy sleeve"
Normally is used to cover a damaged shaft so the new seal has a smooth area toseal against.
I can say I've ever seen one used ona torque converter though.

I believe the 46RE has an output sensor and a shorter overdrive. The RH is longer due to the mechanical governor.

You have a 46RE I'm 100% SURE!

I can't believe it's taken you this long to get it fixed

 

Its taken this long because the 'speedy sleeve' has taken nearly 7 weeks to arrive from the US.
The only reason I have doubts about the tranny is the new seal for a 46RE did't fit and the new 46RH seal does fit (I checked the part numbers).
The sleeve is for the shaft, not torque converter.(wires crossed ?).
Will this fix work or is it just a temporary fix ?

 

It's pretty permanent as long as its installed correctly.

 

I'm getting confused again.
Your leak is at the front of the transmission, Correct?
The front pump seals against the snout of the torque converter.
That's the only place I can see that sleeve being installed on.
It's also possible you leak is from around the outside of the front pump.
There is a large o-ring around the pump that seals it to the housing. It's not common though.
Have your mechanic check the pump to case bolts just in case while the transmission is out.

Here you can see the trans with the torque converter removed.
The Red seal is the pump/converter seal



Here is the torque converter (removed)
The pump seal seals against the shiny snout (stub)
Is this where they want to install the speedy sleeve?

 

Thanks Rabbler, those pics help. Sorry for the delay but couldn't post. The red seal looks to be the one I have. It has since been to the mechanic and replaced. The thing is it was replaced with another 46RH seal (the sleeve wasn't fitted) as the 46RE seal is too small.
Its not yet leaking but no doubt will start.
I'll take a pic of both seals so you can make your own mind up.
Thanks again. (Why are all the small jobs such a pain ?).

 

Well, its leaking again...
The smaller seal has a part number correspondong with 46RE.This is the one that doesn't fit.
The larger seal has a part number corresponding with a 46RH. I have a 46 RE but used the larger seal.
I must have a leak from elsewhere ???? I had a look on some other posts and the problem might be the 'O' ring around the pump or 'bushings' ?????
Any more ideas ?

 

This thread has gone on long enough. Do me a favor bud, i see you have a camera. Please take pictures of the transmission, all over, from every angle. Then show me in a picture the exact place the transmission is leaking.
