Well, a few days ago one of the parts of my car wore out. It's got 213k miles on it (at least, odo went bad at 204+). I've done lots of work on the car since I got it two years ago and I guess if it had to be something, this isn't the worst thing that could have happened.

Generally when I have had transmission problems in the past with cars I'd take it to a specialist. There's a local guy I trust and whenever I see a diagram of a transmission it just looks like a swiss watch with all those gears and stuff, so I've been intimidated to try anything in there.

With this car I promised myself I'd do all the work on it (since it was purchased as a project anyway) and I've learned to do lots of new stuff from clutch replacement to carpeting to some electrical things to seat re-upholstery and all have been interesting and fun to do (more or less ).

So now down to the work at hand: The other day the stick in my car didn't give me any resistance when I tried to go into the 1-r shift plane. It had previously been really weak when returning from 4-5 to 2-3, so I think it was wearing out and it finally went. There is also a leaf-type spring that I've read usually wears out for the reverse lock-out function as well, so I plan to replace both of these items.

I've had no shifting issues so I don't plan to reinvent the wheel and although some would say it's foolish with this many miles, I don't plan to buy a rebuilt or even rebuild it all myself.

So my notes will be here as I work through it, please feel free to comment if or offer up advice or assistance.

Here's an annotated and slightly cleaned up diagram from the WSM.

Reverse lockout spring is replaced- diff cover off

Well, I've got the diff opened up. I cleaned up the outside of the trans before draining it because I didn't want any of the crud from the outside to end up inside.

I guess the trans with the fluid weighs about 60 lbs or so. You can lift it by yourself, but don't plan on carrying it far!

I replaced the reverse lockout spring and put the cover back on to test it. To my layman's touch, it feels like that's the way it was before it went bad. It still rests between 2/3 and 4/5 (which means the old style spring I think) and the reverse lockout is apparently keeping it from going into 1/R without extra pressure (and keeping you from going straight from 1 to R).

Anyway, I had to pull the diff cover to drain it because the drain and vent plugs are seized. I had them out last year to change the fluids but the vent plug is buggered and I don't want to strip it. I'll have to try some Kroil on them and let them soak. At least I can do that on the side while I work on the rest.

Fluid was clean and I had very few shavings on the magnetic plug. I still have to remove the one at the front of the trans.
