Your manual trans will use Dextron III Auto fluid. Yes, it uses Auto Fluid. That blew me away when I found that out. I thought it would have used gear oil, but that is not the case for the Firebird.
Auto transmission radiator has a cooling chamber for transmission fluid to circulate
they're generally on the transmission where the cable from the shifter attaches to the lever on the side of the transmission that changes the 'gear' of the transmission (auto trans). manual transmissions usually have a switch on the clutch pedal (since you didnt specify which transmission type)
Yes shift od with auto trans in nutral.
Gears is what transmission is for. No gears. No transmission!
That would be a 4L80E Transmission.
NO. The transmissions are all together a different design. WON'T interchange.
That would be the 4L60E transmission.
6-speed or 4-speed auto
Auto
I assume this is an Auto. trans. and you have checked the oil. Well, not much to do. Take it to a Auto Transmission repair shop. Big bucks, get an estimate, and look at your options.
drop the transmission pan and change the fluid and trans filter
