Nice quicker shift from 1st to 2nd which is exactly what I needed. Great for my truck with th400.
Shifts to early on 1-2 and 2-3 shifts. Not impressed
Excellent replacement for my 1968 Oldsmobile th400 turbo stock unit
Bought both of these products and they worked like a charm. They were both in perfect condition and worked flawlessly. Received exactly what was described on the product page and very fast on shipping them to me. 5 Stars.
