leave tranny pan off

[dadsbigstroker]

Is it okay to leave the tranny pan off for 2 days. I drained tranny fluid and took pan off to find out that napa gave me the wrong filter. will take 2 days to get in. Also would it be okay to start engine with pan off to get oil sample to send it while I am doing maint on truck. Thank you Brad

DO NOT start the engine with the trans pan off. There is no fluid to suck into the pump and you will trash it. As far as leavint the pan off, it should be ok since everything is coated with fluid. If it is sitting outside, I would prolly put the pan back on with a couple of bolts just to be safe though.

sure glad I asked because I was thinking it would be okay to start engine. I thought I mite have read some where to start the engine to pump out old fluid, but I cant remember for sure.

Yeah I agree. Hide the keys so no one else will start it either. As for leaving the pan off I agree with nova saying to put it on with a bolt in the corners to keep dust and stuff out. I would not leave it off.

put a lock out tag on the steering wheel. no start

Seems like that would make a good mess.

U do not need to start your engine in order to get an oil sample for analyysis.
