so i installed a isspro trans gauge in my truck on sat and i believe it is not working. the needle doesnt move, at all. i have the sensor in the pan. do i have to maybe ground the sensor from the pan to the frame? or is something else the matter? thanks for your help.

 

Is the truck up to temp? My gauge does not read until I've been driving for about 5 minutes.

I had a problem with the wires pulling out of the amp box... they still looked hooked up, but were not.

 

i will look into that mad hat yeah its after ive been driving for like 20 minutes still no movement. so something is wrong. do you have to ground these sensors?

 

also if they are pulled out of the box how do you reattach them? take it apart?

 

I can't remember exactly what the hook up procedure was, it's been 6 years.

On my amp, there were screw terminals on the side for the wires to go in to, you just tightened it down.

 

Is your tranny locked when driving? If so it may keep the temp down pretty low and depending where your gauge temp reading starts you might not see it until it gets hot. Mine starts at 100* F. During the winter, with my tranny locked in town I usally don't see anything above 100* unless it's stop and go. Just a thought. Good luck.

 

I had to ground my sending unit. Also after the truck warms up, put the truck in reverse for a while. That will heat up the trans fluid quickly.

 

how did you ground your trans gauge. also i have a deep pan with cooling tubes on it. i felt the trans pan after driving it in the morning and it wasnt all that hot prolly somewhere around mayb 130? not as hot as a hot shower i could keep my hand on it no problem

 

all the wires are still on there madhat i just made sure

 

I used a piece of wire with a small hose clamp to hold the wire at the base of the sender. Fastened the other end to the frame.

 

i just put a piece of wire on wrapped it around the sender and then tied it to the frame we'll see

 

Which gauges did you get? EV or EV2's? If its a two wire harness to the sender it grounds thru the amp box. Make sure thta is gorunded good and if it does work it could be sender, box, or gauge.

 

yeah i think it is the ev2's im gonna have to go through the wiring tomorrow

no 6 how is the box grounded? do you have to put another wire on it or dont you just plug it in to the gauge and the other end in the sender i didnt see anything about grounding the box? thanks

 

Hmmmm....I thought the instructions called for grounding the box. Is there a control box for the trans temp on an EV2? Oh, I think they use the harness ground to the gauge as the ground for the stepper motor. Thats the way the boost gauge is wired.

 

yeah there is a control box but you dont ground it like you do on the pyrometer i know exactly what your talking about. i lost my trans gauge directions there is no wire for power and no wire for a ground like you would think maybe im wrong ill have to check.
