Wow! What a Difference

[fulleraviation]

I have a new MaxIV with just under 60 hours since Nov. 2007. I decided it was time to change the tranny fluid. I was able to find Type F and the GM additive from Advance Auto. I sucked out the old fluid with a syringe and 1/4tubing and replaced the same way.

Test drive time astonished me! This thing handles completely different. It feels better than new. What a difference!!

The old fluid was like a dark grey. I was able to extract 26 ounces from the T-20.

I cant believe what a difference changing the fluid in my 2 month old Max made.

You can believe me that I will keep it serviced at regular intervals. The stick pressure seems much less now.

BTW: The factory does not recommend synethic fluid or Mercon/Dextron.

Take care,
Rutledge

I was reading about ATF recently, was servicing my girlfriend's dodge neon's automatic. I'm old enough to remember when there was only type F and type A. There are 2 types of automatic trans fluid, those with friction modifiers and those without. Type F is without. If you put anything beides F in an F transmission, it'd shift sloppy.

I always assumed F would require less pressure to keep the bands holding in a T20, chatter aside. The GM limited slip additive was to prevent clutch chatter, and back in the '60s was made from whale oil.
