I have the same problem in my '92 Syncro, but after driving awhile, it is
impossible to select first. I was almost resigned to a tranny rebuild, but
Mark Drillock on [Syncro] (yahoo) offered the following advice:
Trouble selecting first gear only when hot is a common sign of a bad
clutch pilot bearing. Don't be talked into big bucks for a tranny
rebuild until you make sure that this $5 part is not the real cause. It
goes bad and sometimes wears out the input shaft too. These 2 parts can
be cheaply had and replaced easily once the tranny is out. The bearing
is in the end of the engine crankshaft and the input shaft sticks into
it from the tranny.
When the tranny is cold the high viscosity of the tranny oil overcomes
the added friction in the bad pilot bearing. After heat makes the tranny
oil thinner the bad bearing then spins the input shaft even when the
clutch pedal is pressed. This then spins one side of the first gear
gearset and makes it hard for it to engage it's mate gear. If this is
the real problem you should also have similar trouble engaging reverse
when hot.
I referred this to my mechanic, but haven't had time to sort it yet :-(
