shifting without using the clutch?
hey guys i was thinking about this recently.. i was driving a 13 speed at work the other week and those you dont have to use the clutch to shift. i know i know they are comp different trannies and stuff i understand that. but i was thinking if it could be the same with these trucks. ive tried to shift with no clutch with my truck and have no problems doing it... does this hurt the tranny or is it bad or what? whats your guys input or thoughts?

Unless you shift at exactly the right rpm/speed, you'll wear the synchros out as the previous folks mentioned.
It also depends greatly on how much of a mismatch there is between the rpm/speed for that gear when you do shift... the more the synchro works to match the speeds, the more wear on said synchro.
Speaking of bad synchros, the M5OD in my Ranger could use a second gear synchro... it crunches every now and then when I shift into second out of first. Probably from the PO ----ing up the clutch and then driving for a long time on said bad clutch.

Ford tech manuals tell you to make 3 to 4 hard shifts on the affected synchro in an attempt to break up the glazing and rough it up a bit.

'eff Hydro stats. I hate fixing mine when they brake. Warranty ftw!
NASCAR does the same, FWIW, on road courses they don't need to clutch because they have shift points set and they shift at the exact points.
at least thats how it used to be, i knew a guy who worked at a race shop way back when.

It's not hard to do, you're going from 3rd to 4th...ease off the throttle and pull it out of 3rd and depending on how fast your RPM's drop down, slide it into 4th. You do it too fast and you must wait for the RPM to come down...too slow and you have to blip the throttle to gain RPM. That's rough on sychros though.
Heavy trucks are easy because the gears are close. You just grab the next gear, if you're too slow just blip the throttle and it slides right in. No sychros mean you can really do some super grinding if you have no idea what you're doing.
I like when hydros go...as long as they're not mine. They get expensive in a hurry.

I drove like that for about a month when my slave cylinder went (No clutch, period). At the time, it was my only ride so I didnt have a choice until I had the time to replace it. Starting and stopping was, lets say adventurous. Had to coast into the stop sign in nuetral, kill the engine, find first, then take off. Can only get away w/ doing so many rolls through a stop sign. Its actually really easy to do, but then again, I work on class 8 trucks for a living, so floating the gears is almost 2nd nature at this point. Wouldnt recommend it, very easy to ruin your tranny in a hurry, but it can be done.

Just change the fluid and filter every ten years, lol.
