i noticed last night and today my truck is kinda slipping going into 3rd gear under lets say 1/3 thottle. No other gear. On my way back ill see how much the RPM's jump but its not much just a little for a split second. Maybe ill switch the stock computer in and see if it makes a diff. Right before it engages 3rd i hear it rev up then shift.

 

Stock computer in.. Still does it.

 

also truck has 22k on it, I've changed the fluid once.
today i checked it, pink as can be and Full.

 

Warranty?

 

Well after getting some miles back on Stock computer it is acting good again, ill drive it around tonight and see....5/100k Powertrain.

 

Well everything seems good now.
