the converter bolts are in place holding the converter to the flexplate ?

was the converter bolted to the flex plate then put in the transmission ?

Customer: replied 5 months ago.
It doesn't have a flex plate
Expert:  Gary replied 5 months ago.

automatic or stick shift transmission ?

Customer: replied 5 months ago.
Automatic
Expert:  Gary replied 5 months ago.

it has to have a flex plate for an automatic

as the converter is bolted to the flex plate with 3 bolts

a stick shift uses a flywheel and automatic uses a flex plate

are the 3 converter bolts in place ?

was the converter on the engine then the engine put into the transmission ?

Customer: replied 5 months ago.
3 converter bolts. There was no flex plate on it
Expert:  Gary replied 5 months ago.

ok so what are the 3 bolts bolting the convertor too ?

Customer: replied 5 months ago.
They go threw the converter into the flywheel
Expert:  Gary replied 5 months ago.

ok thats fine

was the converter bolted to the flywheel then put in the transmission ?

when in park with the truck NOT ROLL and be locked on the parking lock in the transmission ?

Customer: replied 5 months ago.
Want come out of park
Expert:  Gary replied 5 months ago.

are you reading what i am asking you ?

the fluid is full in the transmission and the truck will not move in any gear ?

Customer: replied 5 months ago.
Full of fluid want come out of gear.The shifter moves but want come out of park.
Expert:  Gary replied 5 months ago.

is the transmission cable and little lever on the transmission under the drivers side moving through all the gears you select with the shifter ?

Customer: replied 5 months ago.
that's working and hooked up.
Expert:  Gary replied 5 months ago.

if the lever on the transmission is moving then it can not be stuck in park

is just the dash saying its still in park no matter what gear you select ?

Customer: replied 5 months ago.
It's moving on the dash
Expert:  Gary replied 5 months ago.

ok if its moving in the dash and the cable and lever on the transmission is moving through all the gears and the fluid is full either the transfer case is stuck in neutral OR there is a pump failure inside the transmission

again was the converter on the engine and then put into the transmission ?

these transmissions when full of fluid and physically being shifted into reverse and a forwards gear should by default have reverse and a forward gear if it does not the transfercase is is neutral or the transmissions pump has failed
