Somewhere I came across a chart that listed all the codes and the cars they came in.

Cool, you got the correct valve body, sometimes people will swap them out with a less desireable one, it's a good trans if built up properly. Mine has lived behind two motors so far and the current motor is in my sig, still running strong for going on six years now.

The ID tag on my trans is the same layout as yours, but if you follow the formula on that website provided by TexasT then your trans was made in 1972 :shock: . Actually that is a good useful link and when I first started looking up my trans I used that site as a reference but the numbers weren't adding up. I had found another website that layed out exactly how to decipher the tag on mine, but for the life of me I can't find it.

So I went out to grab my tag and as I looked at it, it sorta came back to me.

Here is my tag:



If you can't read it, its 265 - 871CZF0117 (I know its seen better days)
First three are the Julian date
87 is the year
1 is the shift
CZ is the model designation(in this case the CZ is for the performance trans for the Monte SS H/O)
F means 2004R
0177 is the production number


This all from the top of my head, if any one can correct me, please do, I don't want to spread misinformation.

This is like a good mystery, and I like to solve a good mystery :lol:

I had mine rebuilt with an art carr rebuild kit and and a gill younger valve body kit(shift kit). I also used a servo out of th200, because it has more surface area to give a firmer hold and shift, by applying more fluid pressure on the intermediate band. I had mine built locally by a guy who had a lot of experience with 2004r, he had a couple in his cars. The place he worked at used to be an independent transmission shop, now its an Aamco.

Lester is just a stock part. I'm not sure, might be the company who made the cover??
