Overheating 3208 in a 90SP36

[Jeff Miller]

No.

With the 250hp in '84, there were some high-ambient-
temp/towing/mountain issues with transmission temperatures, BB
recognized this and offered an upgrade to an external trans cooler like
the '87-'89 had, ... abandoning the in-radiator cooler and adding the
new one to the outlet hose from the radiator.

Running Allison Transynd (synthetic) or Mobil 1 synthetic will lower
transmission temps, it is better at carrying the heat away from the
transmission. For the transmissions with internal retarders I consider
it a must, ... but that's me.

Many people have no problems running with a toad and running normal
thransmission temperatures, and the 4.89:1 gears are short enough that
the RPMs are kept fairly high. If you end up with low RPMs and torque-
converter out of lockup for extended periods, you will see higher temps.

The '84-up models have a transmission temperature gauge, makes it
easier to watch.
