I would stay with the GM manual transmission fluid, Part #88861800.
Dealers do not carry Dexron III anymore, so the formulation you buy at a parts store may not be the same. Do not use Dexron VI.

Redline D4ATF in tranny has been a good one for me. Rear diff is also Redline 75w90, has additive already in as its synthetic. Have also used Valvoline's synth gear oil.
