Exclamation downshifting rumble...clutch problem??

well I dont know much about manual trannies as this is my first of the like. so i figured you guys would be able to help. When downshifting into 1st from 2nd, and only 1st from 2nd, as im putting the car into the 1st gear slot, the shift nob and the car rumbles/shakes a bit. it just started doing this like a week or 2 ago but i brushed it off as i thought it was something i was doing wrong. So, what do you guys think about it?

umm, the only time you should downshift into 1st is at a stop, or a really really low speed and that should also be rev-matched when going down into 1st (meaning bringing up the rpm's to the point to where the engine is already turning at the speed it would be when you disengage the clutch, therefore reducing strain on the transmission and clutch)

Re: downshifting rumble...clutch problem??

The only time I ever go from 2 to 1 is at a complete stop. The easy solution is to stop doing it, because I can't imagine it being good for your tranny.

Re: downshifting rumble...clutch problem??

this is just how I learned to drive a stick. downshift till you stop. I talked to a couple guys at work who drive stick and said that they put the car in neutral and just brake to a stop, cuz its cheaper to replace brakes as it is for the clutch. So my question to you guys is, do you guys downshift through the gears to come to a stop or put it in neutral and ride the brake. im pretty new to the manual world, so any tips would be helpful.

Re: downshifting rumble...clutch problem??

Nuetral and brake to a stop....no need to down shift...there is no rule that says you have to go 1-2-3-4-5-6 to get moving....and then 6-5-4-3-2-1 to stop. I am a 2-4-6 type of guy personally...and only downshift to 4th to slow down when coming down from 50+ mph....but that is only to hear the exhaust.

Brake pads are much cheaper than clutches. I just put it in neutral and coast to my stop.

And then you rev when you get close to being stopped...it was very entertaining at times.

or transmissions.

i downshift till either i reach 3rd and just neutral brake till im stopped, or if im in a agressive mood, i downshift to 2nd then come to the stop. like i said before, the only time i downshift to 1st while still moving is when im going too slow to use 2nd. otherwise 1st is for moving away from a full stop only.

Re: downshifting rumble...clutch problem??

it really depends for me. I downshift, but I don't slam it. Most of the time it's neutral to a stop.

Re: downshifting rumble...clutch problem??

I myself downshift to a stop,I got this from driving tractor trailers and dump trucks, if you go gently you wont foul things up as engine braking is the best braking at times.

I coast the majority of the time.

Then again if I went into 1st in the truck on the road, I'd probably tear things up. It's only good for like 0-15 mph lol

Re: downshifting rumble...clutch problem??

If I recall reading somewhere, that feel you get when you try to put the tranny into first while moving faster than 5MPH, is the tranny protecting itself from you blowing your clutch.

Mine does that rumble when downshifting into second. Nobody answered you about that. Is the rumble ok? Or are my synchros going?

Exactly.

That humming or whining or roaring is your syncro's screaming, "WAIT TILL THE CAR ****ING STOPS BEFORE PUTTING IT IN FIRST." No really, I had a T5 tell me that the other day. Yes I speak transmission.



*side note* I almost put, "I speak tranny," but I knew I'd never hear the end of it

That and the fact that the syncros can only do so much work to mate the engine speed with the transmission speed.

They are probably on they're way out. If I were you I'd take dam good care of the tranny for a while--no speed shifting, powershifting, no downshifting to show off-- and save up and buy another one. Or if you know someone that you trust with trannies, get a rebuild kit and let them rebuild it for you.

Re: downshifting rumble...clutch problem??

You will find that manual tranny cost more to rebuild or can as a single rail can run you more than that of a entire auto tranny rebuild. So enjoy your investment responsibly.
