your transmission is burned out, the 1st and reverse clutches are worn out
If you literally mean the Fastest gear then you get that by collecting junk parts in mission mode then repairing the faster gear turning it into the fastest gear. If your talking about the faster board as in speed wise then that's the high booster which can be purchased at the shop.
Low RPM. Gear is too high for travel speed
An idle set too high can cause a 1994 Nissan Pathfinder to run at a high RPM in 5th gear. A bad transmission gasket can also cause this.
it has a high torque on the first gear plus the first gear is set toward accelerationmor than getting a high speed does this help
When you step on the gas and reach a certain speed the transmission should automatically shift out of first gear and go into second gear. First gear causes the engine to rev higher but gives more torque at the wheels to help the car get going faster. Second gear allows the engine to not rev as high and makes the wheels spin faster but with less torque. The higher the gear the less torque you get at the wheels but the engine does not rev as high. Even though the transmission is not shifting into a high enough gear do not guess that the transmission is the problem because many times the engine is not putting out enough power for the transmission to shift properly. The only way to tell is to put it in neutral and floor it. If the RPMs do not go nearly to the max on the tachometer have the car tuned up fully and see if you still have problems. I hope this helps.
Yes, it could.
If it isn't slipping it is downshifting to 3rd gear
No. In most vehicles reverse is also high gear, on automatics.
The first cause of the jump out from one to other gear is the loose shifter fork, which connects the shifting linkage and gears of the transmission. The second cause is loose shifting linkage itself, which connects the gear shifting knob and shifting fork. The shifting linkage and shifting fork become loose due to the rapid changing of gears from one gear to other at high speed of vehicle. The third cause is the misalignment of shifting linkage to the shifting fork.
It is Probable Ur Clutch Is Gone
I would first check the transmission fluid level.
The high RPMs and cause rapid wear and high temperatures. Overall, if it seems to have broken, then it is broken, otherwise it isn't.
