    I have just stabbed a different motor in my and I was wondering if I could start it with out having fluid in the transmission? I swapped out a bbc for a sbc and I put a new cam/lifters/intake/carb ect in the sbc while it was out and was wanting to start it and break in the cam and make sure it runs before I go any further. The trans is a t56 and I don't have a tail shaft yoke yet so I don't want to fill it up yet. I know on an auto I could simply take out the tq bolts and move the tq back so the trans wont spin. However I've never messed with a lot of manuals. I am thinking that even with the trans in neutral the input shaft would still be spinning right? and could possibly tear up the trans? I did a search but didn't find much

    Well at least you asked before you did it. Back when I was 16 or so I didn't bother to ask anyone and decided to fire up my big block with no gear lube in the trans. (Muncie 4-speed) That was an expensive lesson... :(

    Yeah, but then he would have to hold the clutch in the whole time he was running it. (not great on the throwout bearing either) Just fill it up, so much better and easier.

    Don't do it. I did that once on accident while breaking in a cam. When smoke starts coming out of the dipstick tube it becomes a pricey lesson

    It might make your leg tired but I cant see how it will hurt the throw out bearing as much as it gets used in a lifetime anyway, but yeah Dons rite, if you can wait and fill it up it will be easier.

    With there not being a driveshaft in the trans to hold thing still, even holding the clutch in probably won't save the transmission.

    Bearings and bushings don't like to spin fast without lube.

    Thanks guys, I wanted to make sure before I screwed something up. I will just wait until I can get a yoke then fill it up

    Yes, Mr Obvious, it's er, obvious!

    I remember reading about someone who did that with a rebuilt trans that had never been run, I believe it had lube in it, but it ended up seizing and running the car into the wall somehow or another.
     
  16. Even out of gear, at the least the input shaft and cluster gear are turning and there's a lot of bearings in there.
