80/90 gear lube
5w-30 is the only thing you can use in an Isuzu manual transmission. The way it is designed, if you use 80-90w gear oil, it will burn up the top half of the tranny and the same for the transfer case :)
a noisy second gear in your transmission is that your second gear might have broken gear tooth which is mostly the problem with my cars.either the second gear on the counter gear or the second gear itself.
If you clutch is working fine then try to change the gear fluid in the transmission. My Isuzu shifted hard to and the fluid changed helped alot
If your transmission is manual, you will have to change gear. If it is automatic, you won't.
the synchronize in the transmission is bad, that why the jumping out of fifth gear
Yeah just make sure you have it in neutral. I've heard of people leaving a manual transmission in gear and trying that and actually blowing up the transmission.
3,because the gear ratio in a manual transmission results is a gear ratio of about 3:1 for first gear.
Any Manual transmission can be towed with Manual Gear in Neutral; never engaged in a gear.
That manual transmission doesn't use gear oil. You can use Mercon ATF.
Look at the gear stick, if its auto then you have an auto transmission, if its manual you have a manual transmission.
The synchros are going out on the tranny
