2-3 slip

[joshc64311]

when cold my 5.3 transmission slips when shifting 2-3 trans temp under 150 once it warms up it shifts fine, anyone else have this happen? just curious is this normal when cold rpm jumps like 700-1000.

Mine has a 2 to 3 slip that they tell me is "normal operation". But mine is maybe 300 RPM's. If it's slipping that much I would take it in and have them check it out

Is this a slip that hangs around and gets a little worse as you apply more pedal or is it more of a flash that recovers quickly and is gone in about a second.

just a flash but enough to say wtf

What you have is a flare shift and is common in these trucks. Most people don't notice it until after they put exhaust on.

 

It's just poor TCM programming, fortunately I can tune mine out.

There it is... like Softail, most will report that they have a flare shift.

Mine had a flare on shifts with the stock tune as well. You'll find many 6L80E's have this problem.
