Geartrain noise in 4L60E second gear causing "knock" retard

seems like more than 2 cents there.

i think the idea behind using a 4L80 over a 60 is just because you can buy one, drop it in, setup the calibration and not have to mess with anything else and it will survive behind most any street-driven engine.

i'm also quite excited about the 6L and 6T transmissions these days.... they're not overly complicated to control if you remove the TCM(or somehow are able to interact with it), which is great news for me and my 1227730 based transmission controller.

Yeah at least a buck and a half?

4l60E is fine till you put strain on it like adding HP. 4l80E in stock form will handle it.
