Ok the truck has to be manually shifted or set t o 3rd gear for the truck to get good speed. it doesn't shift on its own. Now i did the obvious for this issue. replaced the shift pack. reassembled and it still does the same thing. so i replaced the valve body and reassembled. new fluid filter the whole shabang. still same issue. now the truck will get up to 50 plus mph. so i assumed that the plates are good. if they were bad i sihould get slipping.
i do have the red lightning bolt on the dash.
My main question is when that shift pack is replaced. do it need to be programmed? cause i cant really see no other option right now. i have another trans sitting waiting just in case but its out of an older truck and the plug in is different. expected because of the age gap.
Do I need to program this transmission for it to shift being as though its mainly electronic? Thanks in advance for all help on this problem.
