The reason it's easier in a rig is because there IS NO syncros. When you shift a pickup like this it's really hard on the syncros unless you get it just so.

Oopsies. I didn't know that.

Again, didn't know that. I'll probably stop doing this then

ya same here. when i stop and take off is the only time. Well, and down shifting. Seems easier to wreck your trans downshifting clutchless (even though i can do it)

I do it when I have a clutch problem

yeah from what I know, you really shouldn't do it with a sync'd trans.

Yup, The really big truck can do it, twin counter shaft transmissions or pretty much any tractor transmission that is rated over ~900ftlbs is a twin counter shaft trans, and inside those transmission s they have sliding clutches to engage the gears and the driver becomes the synchronizer. so there is no need for a clutch you just slide it into another gear slowly when the engine rpms match the speed in the gear you choose to be in.


idk whats on the inside if your transmission though never looked

better be saving up for some synchros. just cause it doesn't grind does not mean it is good for it.
