2001 Dodge Dakota Auto Transmision - No Reverse

From : steve n

Q: good morning i have a 2001 dodge dakota 2wd v6. forward gears are excellent...i can do engine breaking in forward gears... problem is...no reverse. i can hear it go into reverse...like the usual very mild clunk but it does not move. i am hesitant to go to a transmission shop for this...just finished paying $3000 for a transmision for my impala... i would like to know what the most common problem could be based on these symptoms...if it is too much than i will get a used transmission...i hardly ever use this vehicle... does anyone have a hint on what the most likely cause would be... steve .

does anyone have a hint on what the most likely cause would be... rear band... pull the pan and check the rear band adjustment. make sure its not loose/broken/missing pieces that youll find in the pan. next step would be to put a pressure gauge 300psi on the rear servo test port and see what pressure if any you get when you put it in reverse should be around 150psi or so. if you have the ability id do the pressure test first since you can do that must do in fact with the pan on and tranny full of fluid. .

took your advice...i dropped the oil pan and found what looks like a large retaining ring in pieces...looks to have a 4 inch diameter...it almost looks like it belongs with the reverse band... can this be replaced without removing the transmission steve does anyone have a hint on what the most likely cause would be... rear band... pull the pan and check the rear band adjustment. make sure its not loose/broken/missing pieces that youll find in the pan. next step would be to put a pressure gauge 300psi on the rear servo test port and see what pressure if any you get when you put it in reverse should be around 150psi or so. if you have the ability id do the pressure test first since you can do that must do in fact with the pan on and tranny full of fluid. .
