Question: Which tranny fluid is best??

[Dave]

My '01 MN6 has 27K miles on it. I'd like to change out the transmission fluid (still original). 1st to 2nd is a little notchy. Will new fluid help??

Any suggestions? What is your experience??

Thanks,
Dave

I used Redline MT90 in my 88 4+3 trans., I noticed a big difference in shifting. So I went with Redline D4 in my 99 6spd and I didn't notice a big difference. A fluid change at this point on your 01 can't hurt.

I would'nt change the fluid. You will end up with a tranny nightmare. Sounds crazy, but ask around. So many people change the tranny fluid and end up with a tranny problem shortly thereafter.

But mabee that happens with just auto trannys.
