But their is no linkage going too the detent control valve .I have removed the detent cable years ago. I was at full thottle when it happens but doesnt do it all the time.The fluid looks great and is full THANKS.
sounds like a problem in the direct clutch.... the trans is not down shifting , 3rd gear is coming off.
When a t-350 shifts to 3rd gear , 2nd gear remains applied, the roller clutch over-runs. When 3rd gear comes off , the roller clutch engages and you are in 2nd gear again
What is the history on the trans? Fresh rebuild with this v-body? Old trans with v-body change?
