I need to change the tailshaft bushing in my 904. Will the tailshaft come off in an a body without removing the trans? I can't think of any other way to get the bushing out in the car.

I put a fresh one in before drag week last year and it was smoked by the end of the week, has some play in it and leaking. What would cause that? Drivetrain runs nice and smooth. I do have a heavy 3.5" steel driveshaft. I did learn I can clock the bushing differently and get pressurized oil to it vs splash oiling so I will be doing that.

Thanks

it will come off


pull drive saft

remove trans mount , speedo gear

,

remove housing

. You left out 2 steps, remove 2 screws that hide snap ring, use snap rings pliers to open snap ring, pull housing.

I got a bushing remover tool and an installer tool off of Amazon or E-Bay. You can do the bushing without removing the housing. It takes the same tools as a C-4 Ford. I don't remember the toold being very expensive.

Piston ring expender works well for the tail shaft bearing snap ring.

That's good to hear. (Takes same tool as a C4)
I just got a set of bushing drivers from eBay for the 727/518 tranny's, was pretty cheap. I think the front pump bushing is the same as a TH350 or 400 as well

Before removing the housing, placed the shifter in Park and rotate the driveshaft until you hear the parking pawl engage. Makes the park rod (if equipped) slide out of the housing easier.

Great news, thanks for the replies. I will look for that bushing puller first, if I can't find one I will just pull the housing. Just working out of a two car garage I have to setup differently for a small job vs a transmission pull.

Honestly this is probably the most important part of the whole job. You'll thank yourself if you do this part!

If you don't, you'll likely end up needing to take the pan off and valve body out when you go to re-install everything if you forget this step.

I had to take my engine mounts loose, header collector bolts out & remove the trans mount crossmember in order to lower the back of transmission to allow the housing to clear the torsion crossmember above the housing so the engine/transmission as a whole had to tilt down at the back for it to slide off, in my ‘67 Barracuda.

Tool

$91 for the pair on the Bag.

Have you thought about switching to a 4 speed, and getting rid of that maintenance problem child? Probably make your life less stressful.

Yeah this little trans is terrible. All stock internal parts and it has needed 2 extension housing bushings after 3 drag weeks. Total junk!

What about that time it leaked like the Exxon Valdez, backing into a car show? That’s double embarrassment.

HI

tell me how you are going to get pressurized oil to rear bushing by clocking it diff .

no pressure in the area of that bushing ! splash only !

Correct

There is a correct orientation though. You can't just throw them in there.

Clark this ^^^ , there is no pressurized fluid circuit past the govenor, where did you find that info ?

If you are taking out the bushing check to make sure balance of the shaft is good , pinon angle is good and check the bearing in the tailhousing that the mainshft of the trans rides in is not loose

Ok I went back to my email about that. It was not pressurized oiling, but it was suggested I clock the bushing hole at 4 o'clock instead of 12 o'clock because there is another oil hole at that location that might deliver more splash oiling.
