Trans cooler for race car only - do you race ??
If you don't race then regular maintenance of the fluid is important . . .
We were getting temps around 250F in our 915 - our Trans builder CMS recommended
the cooler when he saw what kind of wear we were getting . . .but we didn't put in the
spray bar until this last rebuild . . . should have done it sooner . . . The gears really
don't wear - its the other shifting moving parts and bearings that wear and need periodic
replacement . . . remember our 3.8L race engine lives between 5K to 7K RPM . . .
The pump also will now provide the fluid flow to the new CMS spray bar to get the fluid
exactly between the gears in the correct position . . . this also sprays the ring/pinion . . .
We previously had the cooler just flow the fluid back into the regular fluid fill hole . . .
This kept the fluid cooler but didn't return the fluid to the location where it would
be more beneficial to the gears and other moving parts . . .
We have been using this 915 for 10 years now and this is only the second rebuild . .
