1998 Toyota RAV4 Hard Shift When Cold
The throw out bearing chirps when the vehile is very cold (-20 C).
I also chirp when I am in -20 degree weather. Don't worry about it as long as it doesn't chirp all the time.
Is this a transmission problem? There is no sign of leakage from the clutch slave cylinder. Should I dump this vehicle before this becomes a major problem?
They have a life span of about 80K miles in cold weather country and about 120K in warm climate. Rubber/metal components don't like to move in very cold weather.
There is also the possability that your clutch disc is warn coupled with a lazy hydraulic system causing the problem.
Don't force the gears. The transmission is constructed so precise that I have seen them move in neutral in very cold climates. Let it idle a couple of minutes in neutral, clutch out before you move to prevent transmission damage.
I own a 2006 Toyota Tacoma 5spd and it is a bit sluggish in 25 degree weather.
Good luck, let me know

By the way, I had the vehicle to 2 shops and neither shop was able to fix this problem.
Suggested Repair
Replace the clutch master cylinder and slave (release) cylinder as a pair, then thoroughly bleed the hydraulic line to remove trapped air. Do not rebuild the cylinders; cold-weather internal bypass can prevent full clutch release without visible external leaks. Avoid forcing shifts and let the vehicle idle briefly in neutral before driving when very cold.
Conversation Summary
A 1998 Toyota RAV4 5-speed manual was hard to shift from 1st to 2nd when cold, though it shifted normally once warm. Transmission oil had already been changed with no improvement, and pumping the clutch sometimes helped. The expert diagnosed incomplete clutch release from an internal bypass in the hydraulic system and advised replacing the master and slave cylinders together rather than rebuilding them. After both cylinders were replaced, trapped air remained in the line; bleeding it out resolved the hard shifting. A throw-out bearing chirp only in extreme cold was considered normal if it does not persist.
