Hello everyone,
this may be a little offtopic but I have a 2006 4.8is with 53k miles which is having some issues with the transmission. maybe you can give me some input (much appreciated)

1. pause of exactly 2 seconds before engaging into reverse in drive, park or neutral-I heard something about a release of pressure but why from neutral? or just in general
2. slow to shift when cold from 1-2 and 2-3. It overrevs and then catches
3. when I am coming to a stop to roughly 5mph and then push the gas, the car jerks into gear
4. rough downshift from 2-1 when decelerating before coming to a stop.


Should I re-program the tranny with new software? Any other ideas? I would really appreciate any insight into this
