How do you replace a front pump seal?

It would probably not leak if you were re-using the same converter that came out of it. The only time I've created a seal leak, was by installing a new part into an old seal. I.E. new pinion yoke into an old seal, or new converter into an old seal, etc.

As suggested, not a bad idea to replace it. Pry it out with a seal remover tool. One thing to be aware of when installing a new seal. There is a spring in the seal that needs to stay intact, or you will have a leak. So, with that said, by driving in a new seal, that spring can become dis-lodged, from the force of driving it in.

There are two ways to replace it. With the pump in the trans, or with the pump removed. If you leave the pump in the transmission, and have the right driver to fit over the input shaft and stator support; to drive the seal in, put a bunch of trans-gel or similar transmission assembly lube over the seal spring to keep it from popping out while you drive it in.

If you remove the pump,and disassemble it from the stator support, you can use a regular seal or bearing race driver to install the new seal, of course, make sure the spring doesn't pop out!

Hope this made sense ..... :toothy10:
