How long Can a Rebuilt Tranny Sit? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a neighbor who has a rebuilt t400 with shift kit and new reman converter. it was built I want to say 2 years ago and has sat with only the assembly lube in it. anyone know or have experiance with something like this. can I just add fluid and be good? should the seals be checked? he wants $400. for it and it sounds like a good deal. mine will need a rebuild soon and I know it will cost more.

Where has it been stored? Can he assure you that no water's ever gotten into it? Water will kill the clutches.

I'd think it would be fine as long as it was kept in a dry environment..I kept mine sitting under a work bench from January till May before I put it in the truck,and then it sat there until June before it was used..

I am thinking of buying a muncie 4-speed that has sat for 20 years. We opened it up and looked pretty good, shifted fine.

I'm running a TH350 that I got for free, let sit outside in the rain for a year (the tranny fluid got milky)...it seems fine so far after about 1000 miles and several months but time will tell. If I could get a rebuild for $400...I would be all over it. The last time I checked they wanted about $850+ core charge and that was without any performance options!
