GM Sinchromesh and T-5

1991GT · 07-14-2002, 12:46 PM

Can GM Sinchromesh be used in a T-5? If so is it the best lubricant or is there a better one availible?

Tremecs use GM Synchromesh. You just need to use ATF (Mercon-Dextron II / III ) or any high performance synthetic equivalent (Royal Purple, Red Line)

Yes, you can use GM Synchromesh tranny fluid in a T-5 but any synthetic ATF fluid will do the job quite well.

My car has 130,000 miles on it and sometimes is real hard to get into first gear. Shifting isn't isn't the smoothest around either and I know the fluid has never been changed. My friend has an 87 Fiero and had a very similar issue with his transmission but fixed it when he added the Sinchromesh. I've heard a lot of good things about Red Line's products, you guys think I'd be better off with the Red Line rather than the Sinchromesh?

This is taken directly from the TTC web site.

What type of lube is recommended for my TREMEC transmission?

The following types of lube are recommended:
TR-3550/TKO - GM Synchromesh or Dextron III
TR-3650/T-45/T-5 - Dextron III
T-56 (Ford and GM) - Dextron III
T-56 (Viper only) - Castrol Syntorque

GM Synchromesh is too heavy of an oil to use in a T5. I don't think you would benefit at all from using it, so, yes, looking at Red Line would be a better alternative.

I've known a few people who used the GM Synchromesh fluid in a T-5 without any negative results so I don't believe it would harm an already worn T-5 but as I stated in my first post, any synthetic Mercon fluid would be better.

Red Line is very high quality; you can't go wrong with any of their products.

You can't go wrong with Mobil 1 sythetic ATF in your T-5! I use Mobil 1 prodcuts everywhere and like the fact that they are all available at local shops.
