Slipping transmission
My 94 Explorer's transmission started slipping when it shifts from 1st to 2nd. Is a rebuild in order or is there any other things I should try. I have already changed fluid and filter, but no difference. Where is a good place online to get a rebuilt one? I can remove it and install it myself. Could it be torque converter maybe?

First check out operation in manual 2 and see if it is solid. You should be able to drive around without excessive rpm. This will check the intermediate band. If it is just a late shift from 1 to 2 then it is likely a sticking speed governor which could be fixed without pulling the transmission. Just to mention it, a bad vacuum modulator will cause late shifts in 1 and 2.

I can put it in "1" and then shift to "2" manually at about 3000 rpm and it doesn't slip at all. And if I take off going slightly downhill it doesn't slip, only when it has to pull uphill. Any ideas?
Thanks.
Thanks.

when they talk about transmisions, and most people use it wrong. First I need to know if it is slipping in a gear or just doing a late shift. Seond do you have the logistics and the ability to do a minor dissassembly (not pulling the transmission)?

I don't think its a late shift. The rpm's increase but no increase in speed until it finally shifts to 2nd and they drop back down. Kind of hard to describe I guess. If this doesn't help, I will try again. Thanks.

If 1 and 2 are solid then the clutches are still good. It appears what you are saying is it shifts out of 1 but doesn't go into 2 for a while. Possible but I have trouble accepting that. Usually you have a low/reverse servo that leaks or the intermediate band snaps. If you are inclined you can get a manual at www.bulkpart.com and valve body gaskets. You have checked the fluid level? Has anyone changed the filter lately? Sometimes these are not mounted properly, because of a design change of the filter, and suck in air.
