in an automatic transmission when it shifts the belts that hold the planetary gears that control the gear ratios grab the next gear before it releases the previous gear. while the transmission is in two gears at once the engine doesn't provide the power to the transmission so with the lack of tension on the motor it allows it to build up speed before it slows back down when the transmission releases the lower gear
What about a manual transmission? Is it normal for it to still do this same thing?
After I switch gears in my 98 Saturn SC2 the gear 'slips'. Why?
if the engine isn't reved enough it will stall
In assumption that this question is referring to an automatic transmission a car's engine will not rev over 2800 rpm because when the car automatically shifts as the speed increases that is the usual rpm that the car shifts at. If the car's rpm is getting over 3000 rpm and still not shifting then your transmission is going out and needs to be checked. The autmoatic transmission is what shifts the gears for you. In a manual (shift, clutch) the person needs to shift around 2500 to 3000 rpm. The only reason someone would let the engine rev higher than that for a long period of time while driving manually would be on purpose to burn carbon build up on the pistons.
A bad torque converter can cause slipping gears. The fuel mileage will suffer as well, and the engine will rev higher.
Typically this is caused by the load being removed from the engine, allowing it to rev faster and thus idle higher.
In a manual transmission vehicle, gear shifts work by using a gear stick to change the position of gears inside the transmission. When the driver moves the gear stick, it engages different gears to control the speed and power of the vehicle. This allows the driver to shift between different gears to match the engine's speed with the desired driving conditions.
you could need a transmission flush or your syncro could be worn. try rev matching between gears and if it shifts smooth by doing that its probably your syncro
Could be the gears slipping. Might need new gearbox.
6 e-gear shifts
Rev Like to rev an engine
junk IT
dont rev the engine to much dont rev the engine to much
