rear transmission seal

[matty v]

i used the search button but nothing came up. What do you have to do to replace the rear trans seal when the trans is still on the car????

[E7-S14]

take out the drive shaft/drain the fluid and if im correct it should come out with relatively little problem

The online mechanic section has gone hi-tech, they now have a list you can look at with write-ups for virtually any problem.

(Not flaming, just saying for anyone who looks at this and didn't know)

[1unar3clipse]

1. Drain the Trans

2. Remove driveshaft

3. Use seal puller to remove rear seal

4. place new seal snugly flat in where the previous seal came out of(dabble a little oil onto the seal and sealing surfaces)

5. get a small 2x2 or 2x4 and carefully using a rubber mallet hammer the seal flat like it was when you removed the old one.

6. install driveshaft

7. add trans fluid

8. celebrate your accomplishment with beer

for reference view this post from Positron_'s SR20 Prep thread, where he removes and replaces the seal your asking about.

I received my gaskets and seals today from Courtesy Nissan.

I started with the front transmission cover gasket. I was planning to swap out the front transmission seals also but I couldn't see any way to easily remove these seals without completely dissassembling the transmission and removing the shaft in order to gain access to them.The seals under the front cover appear to be in perfect condition anyway so I just decided to roll the hard six and skip replacing them.Front transmission cover gasket. Part#:32112-08U01I removed the front cover earlier and as you can see it was quite filthy, covered in grease.I got some Mean Green and a scrub brush, cleaned it up and regreased it. I hate handling dirty parts.Start by taking the O-ring and putting it in place.It will go here.Take the O-ring...and place it on the seal, it will stay in place when you put the front cover on.Take a 12mm socket and replace the 5 bolts on the front cover. Torque them to 12-15ft.lbs.Done.Next, I replaced the gearbox gasket. Part#: 32516-03U11.I pulled the old gasket off.Use a razorblade to remove all traces of the old gasket.Take the new gasket...and place it on the underside of the gearbox cover...and place it on the transmission.Use a 12mm socket to replace the six bolts. Tighten them in a similar fashion to the valve cover bolts and torque to 10-13ft.lbs.

I also replaced the transmission rear seal.Transmission rear seal. Part#: 32136-U0100.Seal puller. Wish I had this when I did the front main oil seal.Seal driver kit. This too!Take your seal puller or you could use a prybar or flathead screwdriver and place it around the inside of the seal.Like so.Pull the old seal out.Clean the area.New seal and the old seal.Lubed up the new seal with some gear oil and place it.This is where your seal driver kit comes into play. I couldn't use it the regular way because the shaft was in the way...so I took the old seal and placed it on top of the new seal.I took some of the drivers in the driver kit and placed them on top of the old seal and pushed down to seat the new transmission seal in.Finished.

Sorry for the horde of pictures.
