Guys, I've have a s-1o with a 350 small block and I thought was a th350. Well, when I went to the local parts store to get a new gasket/filter for the th350 it didn't fit. So I went back and the only gasket that would fit, was for a th375?? I am new to hotrodding/automotive in general and I have never heard of this transmission, are they any good??
Hey, thanks killer.. Okay, now for my last question sorry if it's lenghty.. I have been having problems with my truck moving when I put it into gear. Last weekend I noticed the passenger side rear brake was binding (the piston was shot and had press the shoes against the drum) I removed the brakes and off my truck went. Problem solved... NOPE. Yesterday I jacked the rearend up and put it into gear and nothing.. The driveshaft would not spin at all. I then went to my local parts store to pick up the gasket/filter mentioned above because I wanted to look at the fluid. Well I found many small pieces of the gasket in the bottom of the pan.. NOT good... I'm afraid the some of these particals have worked its way into the trany. Is there anything I can do to try to get any of this stuff out. I have had the pan off since yesterday hoping that some of this would drain out. Please know that I have no smarts when it comes to tranies. Any help you can give me would be great, I"m trying to figure out the little problem solving things I can do be having to drop the trany, thanks again.

Is it possible that the filter will stop the debri in the pan from going into the trans? Or is there other places on the trans that draw the fluid from the pan?

Problem at this point is whether the debris is from the pan gasket or the clutch discs. If it is from the clutch discs; then rebuild/replace is next step. If only from the pan gasket; then a good cleaning of the pan and replacement of the filter as well as re-filling the trans fluid may be all that is required.
When re-filling the trans; pour 4 quarts in the trans. Start the engine and while the engine is idling pour in additional trans fluid until FULL on the trans dipstick. Should take about 4-5 additional quarts unless the trans is a new empty one. Total capacity is around 11-12 quarts including the converter, lines, & trans cooler.
Frisco, yes I'm pretty sure the debris is from the gasket. I made a close inspection of the fluid when i drained it and got my hands in there and felt all of the debris and there were no metal flakes of any kind in the fluid. Thanks for all your help. I will put the pan back on tonight and update tomorrow.
sbchevfreak, I don't know much about tranies but I happen to call a local transmission shop and he said a th375 is a TH400 with a TH350 output shaft..
I don't know if any experts will chime in on this..

I use to work in a Chevy parts dept in the mid 70's. Basically the TH375 is a light duty version of the TH400. Same basic trans but I think it basically had smaller clutch packs, meaning less clutch plates, ect. IIRC, I seem to recall a TH425 but I could be wrong. Used in heavy duty trucks.

trans mount on a turbo 400 is 5 inches far forward than a 350, they also made a 375b trans, but it is the heaviest duty of the turbo 350s according to the hydra-matic turbo 350 handbook by ron sessions

sorry about that what i mean is if you have a 350 turbo in a car and you put a 400 turbo in, the location where the 350 crossmember mount was will have to be moved 5inches forward or maybe a little less
Not trying to hijack this, but I have a 350 lockup BOP behind a Poncho engine. Are they very strong, or is the lockup a bad idea for a moderate engine? Never a problem yet.

The t-400 mount area is further back than the t-350 tranny . The cross member would need to move towards the rear of the vehicle.
