Title: Shift linkage issues
Post by: Justin84k10 on February 02, 2016, 09:35:35 am
My truck had been shifting into all of the gears fine and now I have to play with the selector all of the sudden to get it into reverse and park and when I backed it up last night thier was a squeak coming from something. Not really sure how to fix this maybe a new shift linkage? Because the transmission had been working fine before.

Check the nut at the transmission that the lever rod slides into.  It is a 1/2" socket.  More than likely that loosened up.

This bolt seems to have come loose

I doubt it is that one, check where that bent rod that is sorta L shapes slides in the slotted u-bracket on the side of the transmission.  Pull the cotter key, the nut I am referring to is what holds that bracket on the transmission.

But should that one move? The piece that comes from up top at the gear shift moves around a little bit in that slot. I am in process of removing pin currently, it's being tough and doesn't wanna come out.

The rod does not come out of the slot easily, I got it almost out and couldn't get it any more. Is their something special I should do?

Try turning the U shaped bracket.....you will probably have to loosen the bolt that clamps the long rod from the top of the shifter ear.

The U shaped bracket will click from PRND21

That bolt you are talking about is loose, but is all rusted and I do not want to break it. I do have a shift linkage kit on the way though.

It gets to this point and gets stuck .

There's your problem. That rod is supposed to be all the way thru the bracket on the shift shaft with a codder pin thru it so it doesn't do exactly like you have and almost fall out.

I have had mine off several times, and I usually remove the long rod from the equation and I can then turn the U bracket and release the "bent" rod.

if memory serves me it can be removed while in park but neutral or drive un-binds things

justin did you buy the shifter kit off ebay?

I was able to tighten the bolt on the transmission and it still doesn't shift well. When I move the piece on the transmission everything moves fine and it actually goes into park.
I bought the shift kit from an online vendor.

The one I got is like a universal one that requires parts to be cut. I have been playing with the one on the truck a little and have got it to shift a little better. But their is still something not right with it and I'm just not sure what it is.

How good is your transmission mount?  If it is original the trans/transfer case could be hanging lower causing it to bind...

Are all your body line's running even from front to back? I had a similar  issue yrs. back. Cab mounts were shot. My problem was from the column rod down to tranny linkage. All being offset enough not to get the proper throw, as the cab dropped.

My tranny mount seems to be in good shape. Not sure if it's original or not. The body lines of the truck are ok. It had been shifting fine and then all of the sudden it started to struggle getting into park and there is lots of play on the shifter when it's in reverse.

Pop the hood and inspect the rubber bushing on the steering column to the shifting linkage . Is there even one there?

Here is what it looks like currently

from the pictures it looks good but is there play in it?
Title: Re: Shift linkage issues
Post by: Justin84k10 on February 24, 2016, 07:39:42 pm
Yes there is and everything is tight. In reverse the lever moves a little bit and when it's out on park it doesn't really move the selector on the tranny. I'm really stumped on what is wrong with it I'm staring to think that the cab may have moved or settled a little bit or something.

Replaced the main rod that goes from the engine bay down to the transmission and it seems to shift fine now!
