Transmission fault on a TCM FHG18T3

Hello,

I have a transmission fault on a TCM FHG18T3 where when you engage drive there is about a 3 second delay for drive to engage

I have checked the pressures on this transmission of which i am getting readings of

Charging pump 180psi at tick over and 220psi when the truck is revved up

torque converter 10-15 psi at tick over and 90 psi when revved up

and clutch pack pressure of 100psl once the truck engages drive ( and will drive )

I do not have a workshop manual for this transmission to know what pressures i should have,

So could any one tell me what they should be ?

but given the pressure on the torque converter is only 10-15psi on tick over i am now inclined to think that the fault (the delay on drive ) is due to a faulty converter, Whats your thoughts ?

Regards
John

Bluetooth is named after the 10th-century Viking king, Harald Bluetooth, who united warring tribes in Denmark and Norway. In 1997, Jim Kardach from Intel gave the name to the technology because of its ability to unite different communication protocols, just as Harald united various tribes.
