Hi,
Does engine braking wear out your transmission? I use this quite often when I am on the track and don't want a blown transmission :p

that google link is junk, just a bunch of people arguing their opinions.

More wear is put on your gearbox under accelleration compared to decelleration, shift smoothly, have regular maintenance (fluid changes ideally at the same time as you change the engine oil) and whatever you do dont grind/force/miss-shift the gears.

Engine braking puts more wear on your clutch than anything. !

Google is indeed your friend but sometimes it just links you to inaccurate information so need some confirmation from the experts here.

Thanks.
 
:p

Point taken, I just linked the first thing that came up!

You think they are not other 'experts' on other forums out there too? ;)

Sometimes when you search on Google it can bring you here too :)
 
i would of thought engine braking would be sore on the engine

I agree but the clutch is always wearing, even when rev matching, you can never blip it to hit the the exact rpm the gearbox needs to be matched.

would you agree that the engine rpm vs. gearbox input shaft rpm difference is more likely to be greater under an aggressive downshift during clutch engagement than when you downshift during steady-driving?

and would you agree the greater the speed difference between the two results in greater wear?

Interesting topic.



Gee, I didnt mean any offence in sayin that, I was expecting to see a structured or just factual based argument at first.

leek9, i never mentioned wear on the engne as the question was just about the gearbox originally.
 
though you can never blip to the exact rpm each and every time, the engagement isn't entirely perfect either during an upshift ...whether you're just driving normally or shifting at or near redline.

I can't speak for others, but I'm decent and don't vary much during downshifts and I suppose I can say that I've ruined a fair bit of clutches and transmissions along the way to "perfect" my skillset.

If anything, the syncros would likely take the most wear and tear...unless one is prone to ol'skool techniques of double clutching.... you know...like a certain somebody.

LOL. Don't think he will be double clutching that thing:D
 
:D Sure, so RA. tell me what you thing the best gearbox fluid to run is? Im sure youve got more experience on this subject than most. Im due to change my fluids again soon.
 
It really depends on what the application is.

I generally recommend Honda MTF (3, where available) for daily drivers and those who enjoy AutoX.

For those who have high powered road/track cars, it's also dependent on whether or not you are using a clutch pack LSD. If yes or no, we have had excellent results with Torco's RTF.

As always, use a transmission fluid instead of a gear oil. The only exception I can think of is perhaps enduro racing, but today's pure synthetic/synth blends of MTF can take the heat and the shock.
