D&D Performance / T56 tail seal

"The all rubber one goes fully inside the end of the tailshaft. The rubber/metal one is more of a press-in with the metal lip resting on the outside end of the tailshaft."

Not sure what the 'outside end' is as there might be different 'steps' as you move in.

Canrc, do you have the part number you obtained for the upgraded/Viper-spec seal and ordered from Rob at Tremec?

Thanks!
Chris

I have the part number written down at work but this is what the new one will look like:

Sorry to hear that Vince -- glad you get your trans though!

If you could post the part number when you get back to work tomorrow, it would be much appreciated.

Strange, that's a lot different than the other pics I've seen on the net. I thought it would look like the one on the right in the following pic(the standard one is on the left):



And here's a pic of the rear seal on a Viper-spec T56. You can see the metal lip(red):



They look much different than the one you provided a pic of. Are you sure that's the new one?

On a good note Jim from Hurst called me and gave me the new seal part number and Tremec is sending me a Viper seal which is the upgrade.

Raj- Could you post the part number for the metal seal when you get a chance, mine is a leaker also only 700 miles, I checked my vent tube and drive shaft yoke all looks good. Guess is poor design seal.

Thanks Rich

Called Tremec this morning and spoked to Dale and asked him about this issue and if he had the part number for the metal-rimmed version of the seal. He said the following:

"We've heard about this issue with the rear seal and we believe it can be caused by the seal simply not be installed into the tail housing far enough from the factory or that your drivetrain/shaft is too long and it's smacking the seal during suspension travel. Check your seal and see if it seems like it's installed properly. Also, I'll check that part number for you on the metal-rimmed seal and call you back."

He did call me back 15 minutes later and gave me the following part number: 1300-044-017

Raj, is that the same part number you got from them?

I have used D&D in the past with good success. Not making light of your situation, but you may have just caught ol' buddy on a bad day.

[chr2002ca]

Raj, were you able to find that part number at work that you ordered from Rob at Tremec? Just wanted to compare what they told me just in case 2 different persons at Tremec have different advice on part numbers. I hate ordering the wrong part and losing time/money.

Their site says they are the largest 5/6 speed dealers, I am sure they have allot of people that purchase from them and I may have just caught someone on a bad day. That being said his comment of we sell transmissions and not tail seals is what annoyed me since they clearly have a parts section on their site but it is what it is and I did end up getting the help I needed from where I got the t56.

Sorry for not getting back to you earlier Chris but the part number is the same as you listed above.

Going by memory, my T56 mag was ordered 1stQ last year. It has the metal ring on the OD, rubber seal inside that so I would think you're safe Chris.
