Replacing Transmission seals for 4 speed dual range


Recommended Posts

Putting a new used transmission in my hatch, I have new seals for input shaft, rear drive shaft and both side stubs, I figured I would replace all seals on the new trans before I install, but don't know if I should mess with the input shaft, it's harder to get to than the others, and I don't know if they are a common problem anyway. The trans has been sitting indoors with no gear oil in it for a few years, what do you think?

Hi This is Jerry, my question to you is why the 5 speed is so much better trans. I make a kit so everything remains stock inside of your car, if you install a 5 speed in your hatch you will tell yourself why i didn't do this years ago. Thanks Jerry

Input seal requires splitting the case......very difficult on a 4spd.

 

replace all the others.

 

And then get a 5spd when the 4spd craps out.

I didn't realize the case needed to be split! I thought you could pop that plate off that's in front of the front seal, but anyway I did just that, replaced the other 3 and call it good.

regarding 5 speeds, Im well aware of the benefits of a 5 speed swap, I'll take your comments as re-enforcement of that.
