Dry transmission?

[Birdie2000]

My transmission has been sitting freshly rebuilt for about a year now, with little to no fluid in it, 1 qt. at most. Should I be concerned about any corrosion or surface rust on any of the internals like I would be about a dry engine?

Depends on how well the rebuilder prelubed the unit. If he didnt prelube and oil soak the unit i would be very conecrned.

No kidding!!

If the clutches and bands were not presoaked in trans fluid you could be in for some real issues. What happens if the clutches and bands are not soaked in fluid? Moisture gets absorbed thru the friction material and will start rusting the steel backing of the clutch plate or band and the friction material will start lifting off.

Basically you have a 50/50 chance here. I'd run it, you never really know what's going to happen. I have guys tell me all the time that they have had dry transmissions sit for upwards of 5 years with no problems and i've seen where they don't make it 10 miles after sitting a 1 1/2 years.

I believe the builder said that there was a quart already in the transmission when I picked it up, so I'm guessing it's prelubed fairly well. It was done by a reputable shop.

I have a rebuilt 700R4 from my old 89 Suburban, it got used after it was rebuilt but has been sitting about 2 years since it was last used. I kinda wonder if it'll be ok.
