np241 t-case fluid level - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Ok I got an 88 k1500 that had a 700r4 and 241c I think t-case, and now it's got a th350 and the same 241 t-case, thing is I know t-case has a fill plug on the back of it, and I filled it with trans. fluid when I put it all together, and filled the trans. Well I decided to check the t-case fluid the other day and when I pulled the fill plug it came pouring out, had to hurry up ad put it back in.

The truck is in the same place and all as far as being level.

Should it do this? is it dumping from the trans into the t-case? and if so is it gonna hurt? or maybe I had the trans. over full and it came in that way? Should I drain it, by removing the fill plug and let it drain until it stops coming out then check the trans. leave it alone and drive a few days and recheck? or leave it as is. I don't want to mess up anything or blow seals out or something.

Just pull the T/C fill plug and let it drain to that level, replace it and check the trans level. You may have just overfilled the T/C a little, it's not that hard to do.

I guess it's possible but if it drains alot should I be looking for something or worried?
