Trans mainline pressures?
Does anyone know what the specs are for the transmission mainline pressures? It seems these are not only critical but are important in diagnosing trans failures. Thanks for the help.

Transmission pressure tests:
Line pressure for idle in P,N,D,3,2,1 = 64 to 82 psi in R = 85 to 100 psi At stall speed about 2400 rpm, short term or you burn up the clutches unless the wheels can spin. D,3,2,1 = 164 to 182 psi and in R = 206 to 230 psi For the rear section, transfer pressure in D or R = 7 to 11 psi at idle and for stall speed 104 to 114 psi. This is from section 3-2 page 121 of the manual. The transfer case thread size is 10mm (1.0) and a 1/8 npt goes in about one thread. I assume the front line pressure test port is the same size. There is an o-ring under the head of the plug. |

Thanks very much. I hope this info will give me some answers to the transmission's internal malfunctions.
