dry shifting transmissions

[dieselpower99]

i have 99 PSD with six speed is it hard it to dry shift it it heard its bad on secronizers and i heard its good if you make the shift less friction with clutch and saves i, i dry shift all the time is it good or bad

I've never heard of dry shifting. Are you talking about Shifting w/out clutching? If so, it's really not good for your syncros to do that. It puts a LOT of stress on the tranny not using the clutch.

I don't ever use the clutch. I don't see how that puts stress on the trans, unless you're slamming it into gear, although, it does happen sometimes. I've got 238K, probably 75% towing, hardly ever using the clutch, so it can't do very much damage.

fyi, I had a new clutch at about 125K, so I guess shifting without the clutch doesn't prevent much clutch wear

to Bryan. I only use the clutch when taking off from a stop or unless i'm in a hurry. 75% of the time I never use the clutch and have never had a problem with either PSD I have owned.

LOL... I've done this from time to time, don't get to drive a stick much anymore, but if you're easy with it, like was said, not slamin' it thru the gears, don't see how it can hurt... Was drivin' my mom's Cavilier one day, with her in it, told her about shifting w/o clutch, she didn't know it could even be done. She didn't even know that's what I had been doing!

i dont see how its hard semi go 800000 miles without replacing clutch and they only use it to take off

[bryanbrown]

Yeah, so my clutch took a complete sh!t today. Therefore, you may or may not do as I do. Although, it's a oem replacement, and it lasted 120K towing all the time with my mods, so maybe it was just it's time. Probably gonna go with a southbend, I'm thinking conofe.

Transmissions in big trucks are different than those in PSDs, those don't have synchros in them and they cna handle not using a clutch when shifting, but it is also how you do it. Alot of it involves how you shift as to how long a trans will live.

"Strait sticking" is what I know it to be called. I use to do it with my old bronco and would freak out my friends. I spent a lot of my life a truck driver and we only use the clutch to start from a stop. Every other shift I have ever done in a semi is without a clutch.

I would have never known this if I had not read it on here. I really do not have an opinion on this with the exception that it makes sense that it would be the same as the big rigs.
