Over Drive Transmission bushing

Is there anyway to change the rear bushing in an 49 Ford OD transmission without pulling the ****** out of the car ? Thanks Robs
 
The trick is getting the old one out. There are tools for this and I have used them successfully. They are a three flat hooked affair using a slide hammer type puller. If your tail shaft housing has a oil return passage below the bushing you can try crushing the bushing upward toward the center to relieve the tension on it and dragging it out. The correct way though is to remove the transmission, but I get your question.
 
Thanks for info any chance you or someone else on site has a pic of this tool or where i might get one

Don't know that this one is correct for your trans but this is what they look like.

The tool shown may or may not be successful in removing the bushing from the tail housing (which is still attached to the transmission). We always have the housing off when taking the bushing out, and I can tell you that there were times I doubted that such a tool would work. If the bushing has been in there for a long time, they can fight tooth and nail against removal. We generally use a cold chisel and large hammer to drive them in where it just drops out of its tight home. The oiling slot is the place to use the chisel, cutting through it. Usually it gives up and submits before you’ve cut all the way through.
 
I don't know if an early Ford is the same or not but when I was working at the phone company, we had one of those tools above for taking the rear bushings out of the 1970s Ford, Chevy, and Dodge transmissions when they started to leak. It's been so long that I can't remember if those were automatic or manual transmissions that we had problems width? We had an equal number of both types. You'd leave everything in place, but the driveshaft and the tool would pull the bushing right out, it worked really slick. You just need to pay attention to the bushing as it comes out in case there are any oiling holes in it that need to be lined up so the new one can go back in correctly. Also check the fit of the new bushing on the slide yolk before installing it.

Rear bushings!……ahh the stories I could tell. And that’s with the tail housing removed. There was a run of the bushings that was made incorrectly, requiring additional honing of the inside diameter. If the outside diameter is too large it will generally compress the bushing when you drive (or press) it into the housing. That’s when you discover that the new bushing….that fit perfectly on the slip yoke before…..now won’t allow the yoke to slide inside. Thankfully, the new bushings fit perfectly nowadays. We’ve had the bushings go in somewhat loosely in the past so now we add some blue lock tight to the bore of the housing before pressing in the bushing. Of course, the housing should be cleaned and dry inside before doing this. I just can’t imagine trying to do this job properly with the transmission fully assembled, much less with it still installed in the car. Maybe I’m just too anal about such things…..
 
If your familiar with the warner overdrive don't take a chance on it . The transmission comes out easy (not like a mercomatic) and you can if you carful pull the tail housing while leaving most of the OD and trans together . Tim
