Edge converters for a 4r70w are crap. The lockup piston is a stock 245mm gm found in cars like cavaliers. The piston is thin and small with weak springs.
The front cover is stock gm245mm crap as well. The stock converter in these cars is a better unit. Now if you are dealing with an aod or c4 I have no complaints on the edge units. These converters are built froma kit sold by sonnax. You will find many many places build the same exact stuff.
