Thanks nharstad for your input.it really sounds like I have a big problem.I went out and bought all 4 solenoids after I was told that was probably my problem.However, as I said,the scan showed no codes.So I guess I'll have to put 'em up for sale on E-Bay.I've also been told I probably have some sticking valves.Maybe if I just replace the control valve body and maybe the pump also,that may solve my problem...I've gotta try something.It's not slipping or anything it's just missing some shift sequences. It is very troublesome,not to mention 'annoying'...Very puzzling why it seems to shift normal for a few days,then upon leaving for work one morning,it starts the erratic shifting and down-shifting....Very confusing for me ,I must say.
Anyway,thanks for any advice......
