I want to change the fluid in my t-5, right now I am using what for specs.
What are some of your thoughts about going synthetic in the trans?? I am think about using Royal Purple, since I use there motor oil and love it.

Thanks

 

I used Redline synthetic in both my Toploader and then in the T5 I put in. I never had any problems.

I now have a TKO600 and I am using GM Syncromesh, which is what Tremec recommends.

 

I have used royal purple and have absolutely no problems , it was recommended after a rebuild a couple of years ago.

 

I have done so much research on motor and driveline fluids, that it just about makes me sick! Anyway, after all my findings this is what I would suggest:

Motor = Amsoil. There have been several independant tests on several synthetic oils, and this always comes out either on top, with the exception of a couple tests, where it comes in second to best.

Trans = For auto I would again go with Asoil, and for manual I would say RP or Amsoil.

Rear End = Amsoil, Royal Purple or Red Line are all good choices, but my choice is Amsoil, and I always add friction modifier additive.

 

I am a big fan of the good stuff

 

What most recommend on the world wide web is the GM syncromesh stuff for the T-5.Suppost to help the longtivity of the syncro's,and aid for smooth shifts!

 

^^^huh brand X stuff lol

 

Yap,brand X stuff.
Every GM needs a little Ford,and every Ford needs a little GM now,and then. I know......Sounds weird!! But this time round,GM has something good for Ford.

 

royal purple is one of the best u can buy but i would say only but it if u really need it its a hell of a lot more money but its worth it if u want to use it.
