Turbo 400 converter seal

Then you remove 1 bolt that holds the lever that touches the rooster comb. Remove the wide clip on the selector shaft. The shaft should slide out with a little prying and turning. These two parts and two wrenches are all you need to do the actual seal change. Check price and reviews on Amazon.

In this picture I have already removed the nut and gear selector bracket. If there is nothing in the way, then the job just got easier. Next, I took my air hose and blew the mud out of the cavity. Looks like this when it comes out. Here you can see the tear in the seal that I took out. This leak has literally been plaguing me for 3 full years.

Clean off the shaft and the surrounding area. I pre-lubed the seal lip with automatic transmission fluid so it would go on easier. Be VERY careful while putting the seal over the flats on the shaft. If you rip the seal, you get to do it again. Place the installation tool over the seal once it is on the shaft and lightly tap with a hammer until it stops.

Now you are done short of putting everything back together. Share this: Twitter Facebook Pinterest. Pages: [ 1 ] Go Down. Author Topic: Replacing TH torque converter seal?

Read times. Hey guys. Has anyone ever replaced the torque converter seal on your TH transmission? It looks like it can be done without removing the transmission all the way Torque convertor will have to come out completely since the seal is a round seal and has to go over the input shafts. I know you do not want to hear this but something to consider is that unless that seal is hard from heat then there is a good chance the convertor bushing may be worn allowing the convertor to wobble.

If the seal is hard then the rest of the seals in the transmission probably are also and could let you down on the road. After reading you post again I see that you are planning on clearing the input shafts but I would definitely take the convertor off the flywheel to reinstall or you risk doing a lot of damage to the pump.

There are two steps you need to get over in there so you have to turn it a bit back and forth to line up splines and dogs.
