Best Transmission Fluid T56

Hello All I have a 1995 Trans Am with the T56 six speed and a G80 rear end with 238,000 miles on it, it still shifts good and everything, I bought about 3 months ago and I have no record of oil changes and the such, I would like to find out what is the best fluid for the transmission and rear end and if I need any additives for either one.


Thanks Randy Big Bear California

The T-56 uses dexron 3 auto trans fluid. The rear end 80w-90 gear lube with limited slip additive. The best fluids would be the high dollar sythetic ones like Royal Purple, etc.

If you don't have an owner manual, you can download one from www.shbox.com
