Can you adjust the gear rations on a transmission by yourself?

Lloyd: All we need to do is show a little class, a little sophistication, and we’re in like a dirty shirt.
Harry: No problem, Lloyd. We can be classy and sophistic-Oh check out the funbags on that hosehound.
Lloyd: I’d like to eat her liver with some fava beans and a nice bottle of Chianti.

you did the devision backwords the other way you would get a higher number or lower speed gear

high gear is when the input gear locks the output shaft to the input shaft, the gear ratio is the amount of teeth on the input gear and the amount of teeth on the flywheel …there’s actually no power going through the counter shaft even though it is rotating… this gear is where your full torque is being exerted from the engine to the transmission

gear reduction is when a small gear is driving a large gear, this is used in your gears where you need increased torque to move the car from a standstill….. overdrive is when a large gear is driving a small gear, this is used to help reduce work on the engine and help fuel economy …

the output shaft gears (output gears) are the driven gears… countershaft gears are the drive gears…. gear ratio is the number of teeth on the driven gear divided by the number of teeth on the drive gear its in mesh with… the reverse idle is not needed to find the gear ratio for the reverse gear, some instructors tell you that you need it but if you do the math including the idle and without the idle you get the same number

Nice video. I rated your video after watching it. I am running a marketing campaign to start a large auto detailing chain corporation. Let me know what you think by checking out my channel. Thanks

Lot of BS goin on in the background! Sounds like kids dropping tools and the instructor chewing them out!

Good Video, But a reverse ratio has to be a reduction ratio, usally close to the ratio for first gear.. .61:1 is an OD ratio.. The idler is not included to figure the ratio for reverse, it is simply an “idler” to reverse the rotation of the output shaft.

hey is this at a technical institute?

wow kids smart tranys are the one thing that always confuse me
