[Spridgets] Hot stick in slow traffic

Typical running temp for a manual gearbox would be 150-175 F.

Heat is transferred very easily from the engine to the tranny, so you need
to make sure you are  not looking at a more general engine cooling issue.
Do you have an idea what the engine temps were during this excursion?

It might be a good idea to hook up a digital temp sensor to the tranny case
and monitor things.   

After experimenting with the various viscosities in my 5 speed I've
determined the you want to go with the 90w GL-4 oil. NAPA sells it.
Sta-Lube Brand.  140wt quiets the gear noise down but the shifts are hard
until it warms up.

Drove the Midget up to Tulalip (about 18 miles) on some back roads, then the

freeway.  I noticed the transmission and stick shift gets extremely hot in 
stop/go traffic.  We put 30 wt. oil in the trans when we installed it.
Would a 
heavier oil keep it cooler?  Is this a problem?  It got pretty freakin' hot
had me worried.....  Datsun 5 speed.
