My camaro 2000 3.8 while accelerating in constant speed usually this happens in 45-55 mph my rpm starts accelerating or decellerating up and down when that happens i get to a stop and i take off it kicks my gears its crazy and it only kicks my gears when my rpm goes crazy... Checked my trans oil its good
so does any one have any suggestions????

 

is that TBW??? my moms 300 doest the same rpm thing but not the shifting thing that sounds like an electrical problem the comp sounds like it doesnt know when to shift
