After an 'overheating' message at Watkins Glen, I've been told by DRM to put Redline MTL in the tranny. Anyone have any experience with this fluid? How many quarts does it take? Someone told me 13?! Sounds like a lot.

Also, anyone have any experience with DRM's tranny and diff coolers?

Thanks for the help!

 

6 speed or automatic?

 

I've had Redline D4ATF in my 00 ; 6 speed for several years and no probs. Shifts smooth.

I have friends that can't stop singing the praises of Royal Purple's replacement for the Dexron 3 in there six speeds, these guy's were using red line before. Just some food for thought

 

6 Speed trannys will take about 3.75 qts. I switch to Mobile 1 synthetic in my 98 and 02 ZO6 and have noticed a much smoother shift quality!

The Redline MTL does not meet the specifications for Dexron III so if you use this you are stepping outside the manufacturers requirements. Even Redline recommends their D4 ATF for applications requiring Dexron III which is the spec for the MN6/12.

I used Redline D4 ATF for the first 18 months or so of my car's life, then switched to AMSOIL ATF last January. Both of these oils meet Dexron III requirements. My tranny now has something like 16k total miles, 7 DE days, and 24 SCCA races without a problem.

Overheating a tranny is very common on a road course if you drive hard. I did it on my very first DE at Roebling Road with Redline D4 ATF in the tranny. As soon as I got the warning on the DIC, I pulled in and let it cool.

When I had my car prepped for SCCA T1, I had a GM tranny cooler kit put in by Phoenix Performance. No problems with tranny overtemps in two race seasons in the 100 degree MidWest summers I race in. However, note that a tranny cooler is again probably outside the warranty.

As mentioned above, the tranny takes about 3.75 quarts. The drain plug is on the lower passenger side rear of the tranny and the fill plug is about mid-way forward on the driver's side and near the top. To get the oil up into the fill plug I use an oil bottle pump. AMSOIL now makes a nice one that screws right onto their bottles. It is under the "Bottle Hand Pump" under the transmission fluid link on the online store.

 

I have both on my car and they work great.

 

Subdriver.... Just ordered the pump, great idea.
