I need to put a clutch in my 89 F-150 4X4 and haven't figured out which 5 speed trans I have. How do you tell the difference between the Mazda and the ZF transmissions?
The only ID tag I can find reads E9TA BA 645552. Does this mean anything to anybody?

Thanks.

 

I have an 89 F-150 4X4 with a 5 speed. The bigger writing on the tag of mine says E9TA BA and it has the Mazda M5OD. While you have the tranny out, it would be a good idea to replace the 3 rubber plugs on the back of the shift cover. Hope this is helpful.

 

Thanks. Where are those rubber plugs? Where do I get replacements?

 

The plugs are on the back side of the shift cover on the top of the trans. The rubber plugs are a dealer-only item. There are several posts on this forum about about this subject. I followed the advice of a couple of local tranny shops and they both said not to remove the top cover when replacing the rubber plugs. They went in a little hard, but it worked fine. They also recommended to put 'em in dry. There is also a tech article on replacing the plugs in the tech section.
