Product Details
Complaint: Slips after build on either 1-2 shift or 3-4 shift or burns band and / or drum or slips / flairs on 5-4-3 or 4-3 downshift. Cause: Unable to adjust band as no provision exists except to buy expensive gauge tool and 5 different preset length bolts. Superior Correction / FIX: The fix is to install the K0121 and simply adjust the band following our easy step by step instructions. The new adjuster and locknut allow you infinite adjustments without tools or extra parts you won't use.

Excellent product - kept my transmission going for another 2 years.
Sure beats buying an expensive gage tool and 5 different length bolts from Ford. It extended the life of my 2nd-4th gear shift band for nearly 2 years, then band was worn down to metal and had to be replaced by my mechanic.
