how do i put a front seal & bushing into an automatic tranmission on a 79 dodge pick up ?

Answer 1

drop the transmission out and take it to a transmission tech. some autotrans need specialty tools to work on. its better to let a tranny man tackle that job. or you can do a thourough check at
e-auto repair.com I use this regularly. $10 for 7 days and you can print all info for latter review. Good luck

Answer 2

You need to pull the transmission. Then pull the front pump. You will need a front pump puller. You can make one up for your self.

Just get two long threaded rods that will screw into the the two treaded holes in your front pump. Put two heavy sockets over the rods and bolt the ends then start taping up and down until the front pump comes out.

Next take the front pump apart and get a socket that fits the front pump hole snug and tap out the bushing. But first get a seal puller and pull out the front seal.

You will need to get a bushing and seal driver. I would go to a transmission shop and have them install them for you. It only takes 5 min. with the right drivers so don't let them rip you off telling you it's a big job.
Maybe $25.00 he should charge you.

If you try doing it yourself with the wrong tools more than likely the seal and bushing won't go in strieght and you will end up with a leak and winning from the front pump

You will also have to get a new front pump gasket and O ring. The transmission also has to stay at a upright possition or you may lose the band.

Answer 3

You have to drop the transmission out. to get to it. You dont need a pilot shaft bushing for an automatic.

Be careful. It is very heavy. If a transfer case is hooked to it it is even heavier. Definitely heavy enough to squash you. Dont try this if you think you might smash yourself.

Remove the driveline, Disconnect the battery, drop the starter, disconnect the bolt on the transmission to the cross-member, Take dust cover off, unbolt torque converter from the flex plate, disconnect the transmission linkage, unbolt all bolts on the belhousing, put a jack under the transmission and lift it slightly, disconnect all the bolts on the cross-member, and slowly let the jack down as you carefully pull the transmission backwards. That will allow you to bring the transmission to the floor. Next, pull the torque converter out of the transmission.

Seal is now exposed, Remove it and carefully put the new seal in. Put a little tranny fluid on the new seal, Slide torque converter carefully back in and turn it up to 90 degrees until it seats back into the trans. reverse the steps above.

After you've done this a couple of times, you can get to where it takes only a couple of hours instead of all day.

I'd suggest getting a technical service manual for your truck. It explains the steps in more detail and also has the additional steps needed for a 4x4.

For a person like me, I cant see taking it to a shop and spending that type of money for something I can do myself.

fmhgutars nailed it except for one detail. To pull the front pump, just screw 2 of the bolts holding the pump in the housing in the threaded holes in the pump. When they hit the front of the case, continue screwing in until the pump is pulled out.
I am very surprised that a person who worked on transmissions for a living didn't know that.

Answer 5

Pull the trany out and take it to a trany shop. They have special tools just for that.
