Great DIY, OP, is it really required to replace that 3rd roller pin, did you notice any improvement or difference after replacing it?

I realize this is an old post but I just completed the third hole bushings this weekend and thought I would share. To tap the new bushings into place I started out buy using the 232360 drift to counter sink the bushing then gingerly tapped it the rest of the way in with the same blind bushing puller used to pull the bushings out. This worked really well.

For those that have done this job, what were the symptoms that you tried to address, and did this fix solve those? I've noticed that my shifter has a some play in 3rd and 5th (if I remember right), but not nearly any in the other gears. I don't currently have a full on 5th gear lean, but I can tell the centering force on the shifter is less until the car warms up a bit, so I've already been thinking I'll need to do the 5th/reverse bushings sometime in the next few years.

Also, what an epic 1 and only post for the OP. Best DIY with lots of source links I've seen in a long time.

The picture shows smaller but are the 1st gear cover lid (in blue color) and lock ring the same part numbers and sizes as on 5th and reverse?

Thanks for the write up! (if he ever comes back to check on this thread, still his only post).

Thanks for the tip, I was wondering what I was going to use without having the proper drift, saves a lot of digging and possible machining

Yes.

I just did this yesterday, and don't even have the transmission back in the car. But yes, the three caps are all the same. You actually buy three "kits" and wind up with one extra bushing left over.

I couldn't get ahold of anyone with the drifts, but I think I got it done properly anyways. Would have been a lot easier with the drifts.

And wanted to thank the OP for the writeup, and the links to the other sources, all of which helped with their slightly different perspectives.

Here's hoping this (and the rest of the clutch job) go back together properly and leave me with a better-than-new shifter!

Huge, huge, HUGE shout out to the poster for starting this. Thank god this was available! The other things I've read glossed over a few details, which I'm glad you covered! I'm going to get your diagram machined here locally for the detent bushings, so thanks for that!


Damn. I really wish I would have read the ENTIRE first post two days ago when I started on 5th and Reverse.



I had to mangle the pin for 5th just to get it out and I can't find the seam on the bushing.

Well, I just went to go rent a blind bushing removal tool so this better fix all of my problems.

I'm also disappointed to just now learn that the actual detent pin isn't included in the Thayer kit I purchased for the pins. WTF?



Yet another $65 added to the list.

Having an old high school buddy with a machine shop is handy!

Two hour turnaround lol

So I finally got all of my bushings out and pins, just waiting on my replacement stuff for the shift selector to arrive.

The top three were super easy, but 5th and reverse on my transmission (1998 w/ 183,000 miles) were basically fused in the bushings.

I first started with trying to use a screw to get 5th out, but that only got the screw buried deep in there. Getting a new pair of needle nose long enough to reach it was a surprise expense. Bonus: Now I have another tool.

I then tried using 3/8 drop anchors, which worked to get the 5th pin out, but wasn't going to work on the bushing.

Thanks to this thread renting the blind bushing puller is major key.

One pro tip: When expanding the puller to remove the bushing, I found that it's really easy to over do it and then drag the tool along the inside of the steel sleeve, scoring it in the process. This, of course, now left metal shavings inside the transmission. I got as many out as I could with Q-tips, but I'm sure some will be floating around inside the transmission. Looks like a fill and drain will be in order after the car is buttoned back up and driven for a couple miles.


Some pictures of the "fun" for those interested:

















You get creative when you start to get pissed off. Here I tried to use 3/8 drop anchors to get out the 5th gear pin. It worked, but was a pain in the ass:





Blind bushing pulled used to great success:














Tools sacrificed to the automotive gods during this project:



My messy ass work area as I fought with these pins for three days now:
