1870 Code Fix
 

I am going to be changing the valve body soon to fix this code. I found a guide a while ago with some pictures and instructions for applying the fix, even how to tell if a shop has done it before so you can tell if you need the larger reamer and valve, and could not find it again. Would anyone have access to these instructions by chance?
Also I was wondering if anyone had a 77754-R2 Reamer and a 77754-RM5 that they would sell, seeing as you only need it once.

EDIT: I found the guide http://www.sonnax.com/system/instruc...754-04K-IN.pdf if anyone else needs it.

Craby should really sticky this.... This issue is very common in high mileage 4l60E transmissions.

GM has a tsb about this problem.....

Mk posted a link to it in another thread
