3 Speed Tranny Seals??

[Cat Whisker]

Well after overhauling the non FD 3 speed tranny with some new bearings, syschros, gaskets, etc. for a 49 Plymouth with a 52 Dodge engine, I have found that I need new seals for the shift selector shafts. The gasket kit I used did not include them and sure enough after filling with oil on the bench, she's seeping at the 1st-reverse shaft. My book shows the Mopar part numbers as 1127794  and 1134903 in the section of the exploded tranny view. I have found a cross reference for the 11277994 seal as a Fel-Pro number 409 and Fel-Pro 415 for the other one.

 

Has anyone used the Fel-Pro seals and if so, did they work??

 

Thanks in advance.

On the upper shaft I selected an "O" ring that fit the shaft, on the lower shaft I used an "X" cut "O" ring from Clearwater Hydraulics #2-111Q (7/16 x 5/8 x 3/32), the speedo pinion uses a Honda seal #91204-HB3-004

First off many, many thanks for the info. I like the X cut type ring much better and just ordered one from Clearwater. For $2 a piece that a super deal. I also found the Honda seal at AutoZone and will pick it up this afternoon. I feel much better using something tried and tested instead of taking a chance on the Fel-Pro ones. Thanks again and take care.

The Honda seal was a little tight going in, be sure to lube it well.

Thanks for the tip. I'll lube it and be sure to drive it in flat and even.

I touched base with Bernbaum's to see if there transmission gasket set had the shifter seals, nope, nor the speedo seal.

 

Why not?  It's not like O rings cost all that much and it would definitely be a service to the customer.  I also noted that Best Gasket doesn't include them either.

The speedo pinion is actually a seal(Honda) and the lower shift shaft takes a wider "X" cut ring

That was  my problem. I didn't check for the small shaft seals when I got the tranny kit. Now that I have seals on the way I found that this one old Mopar seller on eBay has them included:
