Default 4l60e servo's

Anyone have any input on sonnax 2nd servo in a street weekend toy? I have the sonnax 4th servo and had the vette servo but damaged it so looking to replace. I do have a wide band with stronger anchors Thanks

Installing the Sonnax 2nd apply servo with no other changes will make 2nd & 3rd gear shifts at all throttle openings a little quicker and a little firmer. It will help the 3-4 clutch pack live longer. Look for a possible light throttle 2-3 tie-up. This sometimes happens and you will need to enlarge the 2nd gear band release hole in the separator plate. If little or no tie-up, then you are fine. If you have the transmission apart, then you can make the necessary hole changes and open up the 3rd feed for a firmer WOT 2-3 shift.
