Ok, i was informed by a fellow board member in the lounge that having a stall, and high gears like 2:73's that run the rpms low, is very bad at highway speeds, etc.... because it causes extreme heat development in the tranny...

this makes sense to me... but i've never heard of it...

i have a 10" x 3/4" x 8" hayden tranny cooler made for MOTORHOMES with a gross vehicle weight of up to 31,000 lbs, IN ADDITION to the stock radiator tranny cooling...


is this something i should be worrying about????

i drive on the highway ALOT... and i need this tranny to last a LONG time... (at least 70k miles) it is a QUALITY build made to handle up to 550 hp.

your thoughts PLEASE?

If you have a tranny cooler you should be fine. I have one that's not even as big as yours and mine never get above 150 on my Autometer gauge.

Any cooler is going to help. Get a temp gauge if you really want to know how cool it is. You may be fine with what you have.

the only way it can be really "bad" is if the converter isnt a lockup unit. If it's a non lockup converter,then highway cruising would make it so the converter is always slipping,and that is what builds killer heat,lockup unit's elimintae that problem by not allowing the converter to slip when cruising at a steady speed.

You'll be fine with the setup you have. Dirk hit the nail on the head with his explanation.

i think i have a non lock up converter. darn, this is badddd . btw, just to make sure. a 2000 corvette stall converter is a non lock up unit right, how do you tell the diff. anyhow??

If it's an OEM converter it's most likely a lockup converter. Non lockup converter are meant for drag racing only when torque multiplication is necessary.
