Why is it almost impossible to put the car in first gear at high speeds?

처리 내용

There are physical limits to sychronizers. When you upshift the synchronizer slows the clutch down which is relatively easy. When you down shift the synchronizer has to speed the clutch up which is much harder. Going down just a single gear is not that bad. When you're on the highway, shifting into first is not possible because you're asking the clutch to speed up to well over 10k rpm. That kind of speed is difficult to achieve if not impossible from just a little puny synchronizer. Further the clutch may come apart from that kind of speed. You miss understand how a synchronizer works. The power train is broken up into 3 pieces; (engine up to and including the flywheel), (the clutch - input shaft - counter shaft - constant mesh gears) and (synchronizer hub-shift sleeve). When you push the clutch pedal the flywheel and clutch disc are disconnected. The sifter is connected to the shift sleeve. When you shift the shift sleeve is slid over by the shifter. The sift sleeve pushes on the stru

I have a 2005 Camry that I don’t plan on driving much. First time I have had to consider time recommendations over mileage. Should all time constrained maintenance, such as changing your oil once every 6 months (even if you don’t go 5000 miles in that time) be strictly followed? Opinions seem to vary from person to person. I can see how if you just let your car sit, that it could cause some problems. But I figured if I start it monthly and get up to operating temperature, I should be ok? Moisture can find it’s way into the engine and transmission, bringing it up to operating temperature might

My wife’s car is a 2007 Corolla. She told me the car is making a noise that sounds like a shifting bag of rice. I rode in the car and we stopped at the end of the street and then started into a left-handed u-turn and it sounded to me like we ran over some light gravel/sand on the right-front, but we didn’t - that was the sound. Shhhhhhhhhhhhhhhh. Happens when giving it gas while going into a sharp turn - either direction. She’s not sure that it happens 100% every time, but it does happen regularly. Hoping someone else here has experienced this sound before and can tell me what it is. Thank you

This is in regard to a 1993 Dodge Shadow with a 2.5L engine and 3-speed automatic transmission. When the engine is running, the transmission fluid leaks between the engine and transmission. Is there a replaceable seal, or does the torque converter itself need to be replaced? Once the motor and transmission are pulled, is it very difficult to remove and reinstall a torque converter onto a transmission? E.g. alignment.

WHEN ACCELERATING FROM DEAD STOP IN A RIGHT HAND TURN UP-HILL CAR IS SLOW TO MOVE FORWARD REQUIRING MORE PRESSURE ON GAS PEDAL, THEN TRANSMISSION SEEMS TO BE HUNTING FOR RIGHT GEAR CAUSING A JERKY MOTION.
