What to do when your bike gears won’t shift?
But, if up shifting is still problematic, you should work on the barrel adjuster to turn it anticlockwise. This will increase the tension and solve the problem. If the bike is over-shifting, you will need to tone it down by turning the barrel clockwise (basically, the opposite of what you did to fix the up shifting).
Is it OK to downshift in an automatic transmission?
This practice is not acceptable in automatic transmissions because a forced downshift at high-engine RPMs can result in excessive transmission wear, specifically to the clutch friction plates and the transmission bands.
What happens when you shift into reverse on a car?
Shifting into “Drive” or “Reverse” can cause a sudden, jarring movement on the transmission which increases the stress on the transmission bands and clutch plates. Not only can this sudden movement jolt the entire transmission, but it can also cause damage to other drive line components.

Why are there no forward gears on my 4L60E?
Long story short, old transmission is shot, new transmission that was a fresh build, will not engage any forward gears. Reverse works perfectly. I was wondering what I could look for in the valve body area that could cause this, before re pulling this transmission for a third time to look for burnt up clutches inside.
Why does my car only go in reverse and not forward?
If your fluid is too low, then your transmission may not be able to build up enough hydraulic pressure to shift properly into gears. Automatic transmissions use pressured hydraulic fluid to change gears typically via a car’s computer which activates the transmission solenoid.

What does it mean when your car won’t go into gear?
However, when your car won’t go into gear, or has a hard time doing so, it also indicates that it could be an issue with the clutch linkage shift cables or the computer system. Delayed engagement is a stall of a few seconds when you shift from park to drive.
When this is faulty or not working properly, this can cause a delay in gear shifting or in some cases cause the car to not shift at all. This type of problem is amplified any time the transmission is low on fluid creating a drop in hydraulic pressure.
Why is my automatic transmission not working properly?
A defective PCM could be the reason too. A faulty PCM (powertrain control module) will affect the transmission performance because it controls the gearbox mechanism in most car models. The PCM will have no input if the speed sensor fails.
