I've looked around at some of the other posts and just wanted some carlification.

I'm installing a Autometer Transmission Temp gage this weekend - this is somethign I've never done. From reading, I understand that I can use the diag port on the left side of the tranny - What does it look like? Will this location give me an accurate temp reading or should I drill in to the pan? Any other suggestions - experiences? I have the AutoMeter Model 5757.

I'm concerned about the tranny temp because I pull a travel trailer and I plan on going to Fla this summer and wanted to ensure that this would not be aproblem.

 

Most seem to use the port on the side of the trans. When I looked for it on mine, it just did not seem to be the same bolt that everyone was talking about and did not match any of the pics I saw either......

I wanted to know the hottest the fluid gets anyway, so I decided to tap into the outgoing line from the trans. When I was following the top line that goes into the rad from the trans, I found that the line uses a short rubber hose where it transitions from the crossmember to the rad. I guess for vibration issues...?

I just cut this in half and using a 3/8" brass T and assorted hose fittings and such purchased from Home Depot, spliced into the section of hose. I also used a 12" long high pressure fuel line hose to "loop" around to finish up the splice.

So far it has been fine. I know the fluid temp after it's been through the torque converter and just before it enters the first cooler.

I tow a travel trailer too and use the trans gauge to determine how hard the truck is working. I also put in a REAL water temp gauge while I was at it.... The factory gauges are junk and are only fancy idiot lights..........

Good luck!

 

i am doing the same and have understood that the best place is coming out of the tranny on the way to the cooler. this is the hottest the fluid will get. so i second mitch's design or a configuration of someting similar.

 

You can tee off the metal tubing going into the radiator trans cooler, it's the upper one.

 

OK, I did it - I installed the tranny temp gauge. This may seem to be a small accomplishment to some - but it was a big deal to me.

I used the diag port on the side of the tranny (I was afraid of screwing up if I tried to cut in to the tranny lines as others had mentioned - this was simpler) and made sure that the wire was not lying against the exhaust. I spliced in to the headlight switch for the light on the gauge and piggy backed on the radio power feed for power. I mounted the gauge on the A-post using a regular mounting pod - I wanted one of those nice contoured pods, but could not find one locally and I did not want to wait for a mail delivery, plus I plan on adding a engine temp gauge later, so I buy a double pillar pod then.

Overall, I think it took me maybe 2.5 hours of working time - actual time was longer because I had to run to the parts store for additional connectors and a new test light.

Thanks for everyone’s input.

 

 

mark can you explain the location of this port you are talking about? maybe a pic?

 

Mark, if you have the 4r70w the port is on the drivers side, looks like a pipe plug and it say's line right above it... Pat

 

does anyone have pics of the AutoMeter guages installed at the temperature points.

I have the 3 gauge cluster mounted on my A pillar. I have oil temp, tranny temp and water temp. All are ready to go - however, I cannot figure out how to mount the sending unit sides. I would like the easiest way to mount them and am looking for pictures or a how-to article. My mechanic will finish up I just need to show him what the best route to take is...

Please help.
