Transynd vs Dex VI

[Whitetail Addict]

Mike, I switched over to Transynd in my LB7's 5spd Allison using the "hoot method".

I'm installing the dummy solenoid in my LML. Can I refill it with Transynd? It should take 9 quarts right? The truck currently has the GM Dex VI fluid in it. I plan to do a double drain on it instead of doing the "hoot method" on this truck.

Edit: with 82k miles (bone stock) on it, should I put a new internal filter on while I have the pan off?

No problem. Go for it.:thumb:

Thanks, Mike! I appreciate the help.

Good to hear they are good to mix together.

No, he did a double drain and fill to get all the old out.

Never mix a synthetic oil with a non synthetic oil, it will foam up.

They're both syn aren't they? Dex6 and transynd.

Yeah it is, I forgot, I've never used it.

True story, did it in my race ranger, it would knock and loose oil pressure.

Only time I've ever seen a trans foam was when it was over or under filled.

I learned GM put an exhaust hanger bracket right over the identification sticker on my transmission. So I have yet to get the serial number off the trans so the Allison dealer can sell me the correct internal filter. I'll take a better look when I get it on the lift.

Simple.
Stock shallow pan takes the black filter. All deep pans take the white filter.

Thanks again, Mike! I'll give the dealer a call tomorrow.

I've seen two different black shallow filters. One had a grid pattern on the top side, not sure what the application was but it sure didn't fit mine!

I believe they updated the filter too. I just did my fluid and internal filter Tuesday and my new oem filter was different than what was in my trans. 29542833 was the part number I used for the new filter.

Really?? I've always been paranoid to mix just because of why I've seen them do when mixed in a engine and gear boxes at work and in my ranger.

Guess I should have asked or tried it before assuming.

I wouldn't suggest it just on principal that they have different properties when it comes to lubrication properties and viscosity index ratings. But will it hurt anything? Doubtful.

Thanks for the part number, Josh!
