Here's what I got.
81 Toyota 4x4 pu, 22r, 5spd.
The metal tag inside the right whell well has this.
RN38L - MDA
391KJ21G072L52

I can't find what is the tranny code on any of my charts.

What I am trying to figure out is.
I also have an 84 With the 22r, 5spd with a tranny code of G52
I would like to know if this tranny from the 84 will go in the 81 with no problems. The shifter on my 81 is so sloppy it's hard to find the gears sometimes. I'll Take and swap tranny/t-case as one.

I think it will go np I just don't want to get it all apart and find it won't go.
Ty for any help

 

Visit the Marlin Crawler site.
There is a Tranny ID page (pics and stuff)..

 

the shifter slop issue may be a worn out shifter bushing, which is also available on the marlin trannies page. I do believe some of the manuals used a different bushing setup though

TY both.
I was looking at the pics and the 84 tranny is longer so won't use that.

It is an L52 my 81 has a 4 speed and is a L45
