where exactly do i tie in to test line pressure on my 48re? I'm going to be doing the transgo kit soon and would like to make sure i've got my setting correct.

thanks

 

Pressure Test Port Locations
Test ports are located at both sides of the transmission
case (Fig. 9).
Line pressure is checked at the accumulator port
on the right side of the case. The front servo pressure
port is at the right side of the case just behind the
filler tube opening.

The rear servo and governor pressure ports are at
the right rear of the transmission case. The overdrive
clutch pressure port is at the left rear of the case.




HTH...

 

thanks.
now what would a test gauge look like? the guy at o'reilly looked at me funny when i asked

 

I can't find a pic on Google... but it is a Test Gauge C-3292. I'm still looking...

It looks like it has the correct fittings to go into the test port lines... I cannot see how high the gauge reads.

 

per http://www.sjdiscounttools.com/atd-5550.html
ATD Tools 5550 Automatic Transmission and Engine Oil Pressure Gauge Kit

All domestic cars/light trucks. Most imported cars/light trucks. 3-1/2" deluxe gauge 0-300 PSI/0-21 kg/cm2. 6’ neoprene hose, U.S. and metric fittings. Instructions and Specifications.

 

Looks like it will. Just make sure they have a return policy

 

Is it good to also buy a kit with High and Low gauges? What are the low gauges used for?

 

Hard pipe it inside the cab and leave it, then you can always see what your pressure is.

 

thank you for the diagram its a huge huge help, I was curious though would you or anyone else here happen to know what the pressures at each testing port should be? or are they all the same about 80(ish) at idle and about 100 more at WOT? or is there separate pressure reading for each testing port? thank you all in advance for all the help I have had thus far
