New Viton Low reverse Servo Seals

[Glacier991]

You may recall my frustration at having trouble finding the improved "double lip" seal for the low reverse servo in the A4LD and 5R55 - finally locating it in the Superior Shift kit. Well a friend of mine told me that Transtec had developed a new seal as well... I went to their site and here's what I found - it's true!

New Reverse Servo Viton® D-rings
TransTec has designed two
Viton® D-rings for the reverse
servo found in the C3, A4LD,
4R/5R44/ 55E family of
transmissions. The new D-rings
will replace the O.E. O-rings and
provide superior sealing of main
line pressure, as well as reverse
apply pressure, which improves
reverse engagement.
The new D-rings are available
in kit #4962 and are in stock and
ready for immediate shipment.

D-RINGS

The only question is whether they are available separately. I'll check into that.

Thanks to James in Hawaii!

WWW.TransmissionPartsUSA.Com has both in stock. Here is the information: 23256K double wiper low/reverse servo kit ($1.52), Transtec viton seal kit for the low/reverse servo 23256KA ($2.70).

 

[Glacier991]

I have had a chance to use both since writing that post.The viton D ring seals seem to make a tighter seal than the simple O ring. One advantage they have over the double wiper seal is that you replace BOTH O-rings using the D rings replacements, and JUST the big one when you use the double wiper seal.

 

[BrooklynBay]

I remember a while ago, you recommended the double wiper seal. Would you now recommend the Viton D seal instead of it?

 

[BrooklynBay]

The double wiper only comes with one big one, and no small one in the set? That is odd.

 

[Glacier991]

Yes as between the two I am recommending the Viton D ring seal set over the double wiper. I am sending a set of them with every VB rebuild I do.

An interesting experiment would be to use the double wiper on the big ring seal, and the viton D on the smaller one.

 

[BrooklynBay]

I was also thinking about that too. Do you have any pictures of those seals for a comparison? The Viton D ring seals would last longer than the double wiper rubber seals anyway. I wonder when they will make Viton seals for the internal pistons, like the forward clutch, etc? Do they make Viton seals for the center support? I know that they are made for the 3 governor rings in the extension housing. Those seals have a mitered split. Are the D rings on the low/reverse servo like that too?

 

[Glacier991]

No the D rings are one piece.

D rings

Just wanted to let everyone know that transmissionpartsusa emailed me a short while after I sent them an email and they had some right quick. I ordered three sets since I have three trucks with the same transmission.
I only installed one set so far and reverse works perfectly, goes right in.
Great customer service! Quality Parts!
