Wynn Transmission Fluid

[sswilliams]

Went to the GM dealer to get my tranny service performed assuming they would use oem fluids. Got the truck back and on the statement it said they used "wynn" transmission fluid. Anyone know about this company and does it make quality products. Went to the Allison site and I don't see it on the approved list of fluids.

Haven't heard from anyone so I wanted to bring it back to the top. Can someone help??

Wynn's makes transmission flush machine (fluid exchange)and provides an additive to be used with regular Dexron III that improves it. It will meet higher specs such as, for example, Chrysler 512???

After reading that lengthy thread on Allison Transmission fluid I would contact my dealer, show them the owners manual and ask for proof it is GM "approved" for the Allison.....

I personally would flush it out for Trynsnd....At least make the dealer to put in GM OEM fluid...
