    4l60e gearing ?

    i know this might be a stupid question but i have too ask ,its driving me nuts.did they ever make any diff 1-2nd gearing in the 4l60e trans ,like earlier years or at all.after 5 trans i just got it back and something dont seem right ,my 1 and 2nd dont feel as strong .or could it be open ar closed loop thing ,torque management,idk.?i did retune but im just thinking maybe something didnt let it write tm or looping im not sure ,i just know my truck and something isnt right .like in my tune my shift points are supposed to be stretched out further of course,and now theyre 123 quickly.but if i floor it i do get my high shift points 6200 rpm,etc weird.is this possible for some of the tune too take but not the other part.just wondering guys take into consideration all of what i have written down here.thanks ahead im looking forward too my responses for this crazy thread lol.

    Each tranny will feel a little bit different... Make sure your previous tunes specified the shift points, line pressures, and torque management features. Check to make sure that the tranny fluid levels are were they are suppose to be and give it a little while before hammering the crap out of it. the gearing patterns of the 4L60e should be the same--considering you have gone back to the stock torque converter. Every time you break that thing down and build it back up, it will feel a little different...
