I believe the make a special puller to get it out, but you might be able to use something else, then a socket to install the new one. (assuming that is the seal..it is under where the shift linkage and kickdown linkage all connect to the valve body..)

Use a 15/16 inch socket to tap new one in. Good practice to do this everytime the valve body is dropped, Like doing the water pump when you do the timing belt on a FWD. 12 Grand Caravan 06 T&C 02 T&C 96 Breeze 65 Barracuda "S"

Pull the pan & drip the valve body, while your there replace the kickdown lever seal & the dipstick "O"ring also buy the reusable pan gasket at your Mopar dealer...

Agreed, you might as well use a hole saw and cut your floorpan to get access for that tool. Dropping the pan shouldnt be a problem with headers, just a little dirty.

As mentioned drop VB & can use some allthread & flat washers & socket to draw the new seal down from the top(& poke the old one out from the bottom) live every 24 hour block of time like it's your last day on earth

There are 2 seals , both require linkage removal and one MAY require you to remove the valve body . There is a seal in the case , that one can be done withthe special tool , there is also one between the gear selector and the throttle valve control shaft , incorrectly called kickdown , that one you ony need to remove the top lever , an e clip and the washer , seal is under it , becareful you don't let it drop should you decide to try it with the VB in the trans . clean the shafts and that area good before pulling the seal that way you don't get dirt in under the seals or damage the seals sliding them back over rusty gritty shafts .

Is it an o-ring or seal? Any help with a p/n of some sort.I replaced the shift shaft seal with marginal success,so Id like to replace that seal also.Not to hi-jack but thanks for any info.

Where can I pick up one of the small seals? I had a hard enough time getting someone competent to look up the shift shaft seal.
