Sonnax adds a small 2-3 accumulator support plate on '01-later 4R70W valve bodies. The addition of this plate eliminates separator plate cracking and cross-leaking.
|The '98-'00 will have a hole inside the plate. See the arrow above.||'01-Later will have a hole just to the rear of the small plate. See arrow above.|
