trannys screwy

e4od with 177,000 miles on it. Driving it last week it wouldn't go itno 3'rdfrom second to fourth- second at like 3,400 rpm's then tc lock and Od shift. Rest of the shifts where sloppy. next day was better only did it twice instead of all the time. Next day while in 4'th the tranny would jump to nuetral. If I cancelled the OD button it went into 3'rd then hit the button and back to 4'th. No CEL or OD button Flash. New fluid and filter and sonnax Shift Kit 2 months ago.

Any Idea's

Thanks Guys

could be as simple as a sticking valve, does the sonnax kit involve replacing the accumulator springs? i'd start there

No it reuses the springs but gives shims for tension and replaces the actual valve. I beleive the valves are grooved to allow fluid to leak past, kind like drilling the VB. Would that explain the drop into neutral?

i'd start by dropping the body and check for sticky valves. if they feel good remove them and look for a burr or abnormal wear marks on the valve and in the body
