Default input shaft oil seal replacement

Just pulled my tranny ('91 FWD 5spd) because it's leaking gear oil everywhere from inside the bellhousing. I have a new input shaft oil seal as I believe this is the only place the oil can be coming from. I was hoping I would be able to get to it and replace it myself but it looks like the bellhousing has to be seperated from the tranny. Is this the case?

Thanks,
Brandon

yes, the bellhousing needs to be seperated. it is not too hard to do, takes about ten minutes to seperate the two. There is a bearing that needs to be pressed out then you can change the seal.

I got my OEM seal from 3SX. Not sure if it's the same for all or not. Ended up taking the tranny to a shop. Opening a transmission scares me.

Bringing this thread back to life.

I have the same issue. First I thought I had a rear main seal leak but it is gear oil leaking out. I added a UV dye to the gear oil and it glows where the bell housing and block meet. So....it has to be the input shaft seal.

What is a fair price to pay a transmission shop to change this seal if I take them the OEM seal and transmission (removed from the car)?

Also, should I have them replace the bearing that comes out.

Part numbers of the bearing and input seal please.

For a 94 FWD 5 speed.

When I did mine didn't need any presses, just take it all apart, replace that seal and put it all back together.

Build dates 1991.08.2 and up is MD741818. You're welcome :P

Thanks.

When you say take it all apart....pretty much everything in the transmission has to come out?

Or

Can just the input shaft be removed to make the fix?

I've done internal engine repair on other cars but never opened up a transmission of any kind so I worry most about lifting something out, having parts fall, and not knowing how it goes back together.
