Can you change it in the car?

Yes.

You need one of these tools.

Make your own, use a socket or washer that is the same diameter as the metal can of the seal, and use a bolt and nut with washers.

Just carefully align the seal and start turning the nut.

Can it be done in the car?

You can do it. Not super easy. I have done it with a pick or a small screw driver to remove and tapped it back in with a socket and small hammer. I think if you have the right size C clamp it can be pressed back it.

When you buy that seal, which isn't real expensive, buy two. Good luck.

Yes. Like I said earlier.

Just go slow, line things up and slowly tighten the nut from the bottom, bolt in from the top.

Make sure the seal is centered in the countersink of the case.

You can easily knock the seal out from the bottom.

You need to remove the valve body first, I assume you know that.

You can replace it in car like others have said. The advice I would give is buy 2 or 3 seals before you do the job. You may ruin one pressing it in place. I did this in car and ruined two, third one was the charm. I bent up the seal housing because things were not centered correctly.

The tool I put the link to doesn't require removing the valve body.



The one on the right in the pics is for removing the seal, all that is required is removing the shift lever and throttle pressure/kickdown lever.

The one on the left is for installing the seal.

I've had one of those seal remover/installer tools in my toolbox for almost 40 years, it's come in handy several times.

It's designed to make replacing the seal in the car much easier.

Perfect! Just ordered a set, thanks for this.

Anyone have any suggestions for good seals? Some of the seals and bearings we've been getting lately have been less than crummy.

TIA!

l have some mopar 2466842 NOS seals.

The hardest part of replacing the seal in the car is that its difficult to see what you are doing. Its tight in there so you kinda have to feel your way through the job. Dropping the crossmember and letting the tailshaft drop a couple inches gives you a little more room. Watch firewall while lowering, small block distributor will hit first.

Bought the tool.It shredded the hard seal.Now what. I don't want to remove the valve body.

I have pried them out with a small screw driver before.

Did you get it threaded completely down into the seal before you started tightening the upper bolt to pull the seal (and the tool) up and out?
It should bite into the metal ring part of the seal when threaded in completely.
That's what pulls that part of the seal out, just threading it into the rubber won't.

i know you really don't want to remove the valve body, but it isn't that hard to do.
just my opinion, your mileage will vary.

Got it Took was crap. Pried it out with a small screwdriver. Not fun but it's done. Thanks for the help.

Your welcome.
