After the vehicle (05 Ram 1500 with 142,000) has sat for a period of time (minutes to hours), when you start the truck and immediately put it into gear, it feels like the transmission is not engaging for a few seconds. I took the truck to a "certified" shop and they indicate that the truck is acting normal doing this. They sited a Dodge service bulletin that says that when the vehicle is turned off, the transmission fluid drains into the transfer case. When started, it takes 5+ seconds for the fluid to be pumped from the transfer case to the transmission thus the feeling of the transmission is slipping when the truck is started and immediately put into gear. They tell me that I need to start the truck, wait at least 5 seconds and then put into gear. True or false?
My car has 142000 miles.
My car has an automatic transmission.
The transfer case has its own separate oiling system and does not share fluids with the transmission. The transmission may be having a problem with sucking air from a leak in the valve body or a front pump of the transmission. Have the transmission pressures tested by a transmission repair mechanic or shop. You first should make sure the transmission is full of the correct fluid and then go from there if the problem continues.
