I'll have to go back and see about finding some trans gauges. Once I get the money I'd like to do a dual pillar gauge pod with dual trans temp gauges. A in and out temp.

 

Dayum! Got pics of that?

 

I've seen those that's why I wanted to ask

 

Doub't u'll find a trans temp gauge......a coolant temp gauge and the corresponding sending unit that goes with it (very important) plumbed correctly should work fine. Fluid temp out of the tranny is the important one.

 

at one time you could buy aftermarket transmission coolers that have a built in thermostat, & they would bypass the cooler until the fluid temp got to a certain point, & then it would allow it to go through the cooler.

 

That's a good idea. Maybe harbor freight has some

 

Our cooler is no where near the size of the rad but rated at 19,000 lbs GVW, IIRC.

 

why do you say that? both B&M and autometer make one. i'm running the B&M one in mine and have been for 6 yrs now. the B&M one even comes with the line fittings and wiring.

 

I was presuming the OP was talking about finding a factory tranny temp gauge (post #16)....and referring to the OP going to his local JY and getting the temp gauge out of the ZJ he's been removing parts from.

 

i found like three different sizes at work

 

Oh there's more cars than just the zj's and xj's. I'm sure there's a totaled truck that has some of these. If not oh well but it's worth looking

 

if your not hauling a stock cooler should do just fine, it doesnt hurt to install a temp gauge. In mine i had an autometer mechanical temp gauge mounted in the pan with the gauge at the bottom of my A-pillar combine with B&Ms largest cooler i think its like 7x8x1, i ran large as i had an old tent trailer that weighed in around 1500Lbs and having 3.55s with 32s had a tenancy to produce a fair bit of heat more so than the old AW4 can handle. on you typical day running temp was around 200*F.........over heated it a couple times though but thats my own doing in pushing it too hard and not paying attention to my gauge, 230-240 she starts to slip by about 260 you loose almost all power....

if you want pics i have some of the gauge and probe location, give ya some ideas.

 

I plan on towing a boat a small off road trailer. But I will be towing a trailer.

 

If you could post where the gauges are that would be a big help.

 

Dayum, those are some toasty tranny temps and those are the fluid temps after the fluid has been thru the cooler(s).....sending unit should be mounted in the fluid line exiting the tranny (the hot fluid)......kinda like engine coolant temp is measured where it exits the motor, not where it enters.
