How can you tell the difference between a 47rh and a 47re?
How can you tell the difference between a 47rh and a 47re?
The easiest way to tell the difference is the plug where wires plug into trans coming from PCM. The RH has a 4 pin not quite flat like a trailer connector and the RE has a round 8 pin plug. The RH uses an external fluid temp sensor while the RE has a thermistor inside of the governer pressure sensor.
Why do you need to adjust the transmission bands?
When applied, the bands tighten around drive components to hold them in place. To apply exactly right, those bands needed to be adjusted properly. Transmission band adjustment used to be a regular part of a basic transmission service.
How is a steel band applied to a transmission?
The spring-like nature of the steel band helps keep the end gap at its widest until the band is applied. Like most physical movements in an automatic transmission, the band is applied by hydraulic pressure. Valves in the transmission govern the timing of fluid pressure on a piston, or servo.
How do you adjust the band on a Dode Ram?
Hold adjusting screw in place and tighten lock-nut to: The adjustment screw inside the case is a square head bolt. You will need a 1/4 square head socket to fit your torque wrench. (this may also take a 1/4″ or 5/32″ six point socket) o 42RE – tighten to 72 in-lb, back off 3 turns. (TSB 21-16-98) or 1-1/2 turns, for V-10 vehicles.
How does a servo push rod adjust the band?
The other end of the band is held stationary by a fixed rod, and this device, or the servo push rod, is the adjustment point. Typically, the threaded rod passes through the transmission case to allow external adjustment of the band end gap. A band that is adjusted too tightly will displace the fluid that prevents friction material loss.
