Tranny guage problem

[MONMIX]

I just instaled the Perma Cool tranny temp guage in my Ex and it doesn't work.
I hooked it all up and started the truck, I had illumination, and it worked off the dimmer ( thanks Alec )
So I buttened things up and drove home.
Not I can not fathom even in this cold, even with my second auxaliry cooler that my tranny did not go over 140 degreese, which is the lowest reading on the guage. I have 12v at the light terminal and at the power terminal.

Any thoughts on where to look ?

Oh, if any body cares the Auto-Meter stering colom guage pod is a PITA to instal, but still looks cool.
( pics soon )

Umm... My tranny temp gauge only reads down to 70 degrees, and recently when I have gotten in and started it, the gauge flashes "32" briefly before changing to a scrolling "Lo" (What it reads when the fluid temp is less than 70). Very rarely have I seen it exceed 140 in the summer in stop and go traffic. Usually it is around 120. I think it is entirely possible that you have not exceeded 140 in this weather.

Yeah the sending unit is the ground.

It is a shock to me that Perma-Cool would sell a tranny temp guage where the lowest reading ( 140 ) isn't a operating tempture.

I guess I need to hunt down a lower reading guage ?

The lowest reading on my Autometer gauge is 100 and I rarely pass that unless I'm driving for more than 20 min at a time. If I drive like a maniac for 5-10 minutes, it'll get up to 150-180.

Where is your sending unit located? Must be after the tranny cooler for those low readings.

It's on the driver's side tube, I believe, right before the cooler. Before I installed it I drove around for a while and then felt which tube was hotter and used that one, since nobody could say for sure which was which on a '94.

Mine is pre coolers.

That wil yield a more accurate reading.

 

[MONMIX]

Which is why I did it that way.
Yes I did mean coolerS ( plural )
The path is filter, factory aux, B&M aux, radiator ( if memory serves me correct )
Is is possible I am running below 140 ?

I have been looking around and it seems most tranny temp guages start between 100 and 140.

I would hate to have to buy a new guage.

140 F is very possible on the highway or for short runs in town with cold ambient temps. However, in stop and go traffic I would expect to see 160 to 180 F.

Well I guess I can hold off till summer, see if it moves at all.
Summit had a few that were very affordable and started at 100.

Everyone, thanks for your help and input.
It is so cool having a site like this where so many people work together to help another guy solve a problem.

I really like digital gauges.

 

[MONMIX]

I would go digital too but the rest are analog and I like the continunity.


Hey, I'll be in your neck of the woods later this week.
( Lakeland, Tampa, Orlando what have you )

I'll have to look for you and thank you for the help.
Buy you a beer or a soda or a cheese burger.
