Ive had my tranny temp gauge installed for awhile now an have yet to see it move i have the accutemp thing from genos installed, had the truck half way to oporating temp tonight got under it an the tranny lines were warm but not hot, so im thinkin either the gauge is broke or im not gettin it hot enough to show a reading so could i take a match an hold it near the end of the probe an see if that makes the gauge move? Next question is the truck is an 04 california 235hp with the cat its an 04 mechanical wastegate. the exaust has a 4" tail pipe diamiter but where ever to pieces are connected (tail pipe to muffler delete- to cat- to DP) its 3.5" diameter, will a cat delete pipe for an 04.5 work on this truck? Ialready have the muffler delete soi didnt know if my exaust was the same size as those found on 04.5 trucks an if the cat delete works with the muffler delete installed
thanks for any help you can give

 

A heat gun might be prefered, but the match thing should give ideal. You might check with multimeter and see if have a viable circuit.

 

i thought i saw on this site or another, that a wire should be installed under the clamp(bare wire or terminal) and then terminated to a good ground. after this, the gage worked

 

thanks ill try heat an see if that works if not ill try grounding it. So noone knows about the exaust?
thanks

 

alright i grounded it nothing, heated it up, nothing am i missing something, also the cat on my truck is differnt then 04.5 so i dont know what to do

 

I have the same accutemp sender from Geno's. I installed it last summer and it worked fine until it got cold outside, now when Im driving on the freeway the needle wont move at all. But when I drive around town, it will move up slightly, but not where it would if it was warm out.

 

For the exhaust get a 4" elbow from a 04.5+ and a 4" TBE exhaust for a 04.5+..

 

This time of year in upstate NY, unless you're hauling a big load the trans oil won't get hot enough to read on most electric gauges. Most gauges start reading around 100* or so. I have an electronic gauge, and my trans temp never gets that high.

I looked at the Genos site, and didn't see anything for accutemp.

Generally speaking, an electrical temp gauge is a very simple device. It's merely a volt meter, with the sender acting as a variable resister.

There are a couple of ways to test the gauge. Use a 9v battery, and hook the neg side to the "sender" post of the gauge, and the pos side to the "power" side of the gauge. The gauge should read about 3/4 scale.

To test the sender, remove it from the truck. Use an ohm meter to measure resistance between the body and the terminal post. Put the sender in hot water (like 150-200*) and measure the resistance again. If it doesn't change, the sender is bad.

If both of those tests are OK, then the problem is in the wiring. Where is the sender mounted? If it's on the tubing, the ground isn't good enough to be accurate. If it's in the pan, it should be fine.

If it's a mechanical gauge, remove the probe and stick it in a coffee cup filled with boiling water. If the needle doesn't move, replace the gauge.

 

alright thanks ill try that
