1st gear not engaging over 8km/h, gearbox Options

[phelps]

hey guys

ive only had my zr for a month and have found unless you are driving under 10km/h the car wont shift into 1st gear.

there is no unusual noises it just wont go in...

is the car made to do this or is it a problem?????

cheers phelps

phelps... sounds like you got a synchro going out thats going to your fourth gear.

and to the rest trying to downshift into 1st gear. First gear in this transmission is not synchronized so it will not go in unforced or unless your doubleclutch/ or are perfect on your revmatching will it go in. it is a saftey precaution so that you dont through your tranny out onto the street, or put your rods through your engine from bouncing. The gear ratio's in the 6th gen celica are really short... i believe something like 4.27.

another tidbit of information:
Synchronized gears (2-5th) in our cars help match the transmission speed and engine speed to the gear you are using, thus making it so you dont have to rev match.
Un-synchronized gears, do not have this and therefore do not help match the speed of the engine and transmission gears to each other.
