Replacing bushings on the auto trans.
« on: June 20, 2012, 01:30:26 »
The bushing on the auto trans. that connects the gear shift to the gear selector is bad and I need to replace it. I need to either move the gear selector in order to match it up with the gear shift, or take the trans. cover plate off. Has anyone had to replace this nylon bushing?

I did mine last weekend. 

If it is the one that connects the shifter to the rear end of the linkage you can remove the carpet that covers the tunnel from the interior and then the shift gate plate with 4-10mm nuts and pull it through the hole and access it that way. 

If it is the bushing on the front end it should be accessable from under the car.

I find it easier to put to bushing on the female end first and then snap the male end into the hole.

Good luck.

Thanks Bill. It is the one underneath. It came off and is not easy to get to because of the transmission plate. I will try to move it into position with a pair of pliers or something to pop the new bushing in.

A touch of white grease helps pop on the bushing as well. Spray silicone would also work.

Thanks. As it turns out, both bushings are very bad. As I was trying to pull on the selector rod, the bushing at the gear shift came off. It looks like the bushing at the gear shift might be harder to get to and put on, so I think I will line up the selector rod and put that one on first. Any comments before I start on this tomorrow?

Looks like we have been down the same road together on our pagodas.  I had the same problem.  I took off the long linkage arm from my shifter to the trans linkage from below.  I noted that a previous owner had drilled  a very small hole on the stud that the bushing slides over.  There was a tiny cotter pin that was holding the linkage on.  Bushing was shot, so that cotter pin was the only thing holding the rod to the shifter.    What a great idea I said!  So I drilled a hole on the transmission linkage stud as well.  Do a search under my name and you will find my post on the procedure.   You must drill the holes in exactly the right spot.  Do a mock-up before you drill these holes.  No room for error.

 I do not see anyway you could drill the stud on the bottom of the shifter while mounted in the car.  Shifter would have to be removed.  On the Trans end, there was enough room to drill the stud after I supported the trans, and removed the trans support plate. 

With those cotter pins installed on both ends, you will never be stranded when the bushings go south.  Happened many times to other owners.

Let me know if I can help further.
