Trans TEmp Gauge

[GTSailor]

Does anyone know if this trans temp gauge fit in original dash. it is part# 3519662C1. There appears to be extra spots in the International 3800 dash circled in pics below.

i really rather not have other gauges if there is one that fits.

And I think I have read most people put gauge on outlet going to cooler/radiator. i guess that's the hottest it would be. the inlet from cooler/radiator would be the coolest, right?

And while I am at it maybe EGT?

Anyone seen a gauge cluster with the left 3 and the lower right ones with anything in them. Is there an original location. it looks like these gauges plug into a board and maybe the wires from sender land somewhere else.

I had a pop out circle right above the key ignition area, and to the left of my gear shift. I hole sawed it a bit bigger and just used a generic gauge. Works good!! No matter what you end up doing...its a must. And fyi....what about adding flat plastic and/or trimming to make it fit?

I have a 1999 3800
My gauge cluster has a trans temp and a current gauge on the right side

Curious if you learned anything on this?

the trans tempo gauge will plug in to the lower left position on the cliuster (or one above.. I have to look).. if the harness is already there it eill be a 2 pin connector likely rolled up i nthe harness above the transmission.. the sensor went into the side of the pan on the AT545 and MT643. I dont klnow if the same is true on the later clusters with the rounf gauges.. the allison 2000 series and MD3000's habve internal temnp sensors and that data is sent acrossthe J1939 link.. the place for a trans gaiuge may still exist but ive never messes with it on the newer cluster..

Thanks for the part number on this, I wanted to upgrade my gauge cluster as well and do this. I couldn't find the part numbers for them individually.

The real trick is finding the right Sender that outputs the proper signal foe the guage...

Depends which question...

The other gauges i know of are:
on left from top to bottom rear end temp ( i think for two speed axles), trans temp, and amps,

On right I think:
Brake pressure (air)
Egt? Boost? not really sure.

You don't happen to have the AMMeter gauge part number do you? (Amps meter)

i used 3803848C1 but so far I have not gotten it to work. I think the gauge cluster is not being fed any power. i need to do some more testing.

[cadillackid]

I show the gauge as IH part: 1690264C1
and the sender as IH part: 1675751C1


those are for my 99.5 chassis (00 body) 3800.



on mine the sensor was in the pan opposite the dipstick.. however the Book shows the sensor going into a 'T' fitting at the top of the transmission on the "out towards cooler" hose.. this is presumably some of the hottest fluid you would see .. I know the transmision in my red bus was swapped at least once before I got it so the sensor couldve been moved at that time...







just to clarify



the gauge fits in the middle slot of the far left section of the cluster.. the far lower left is the AMP gauge..


this is the way the book shows and the way my red bus is built.

i am getting all kinds of part numbers. 1690290C1, 2037892C1. the first one seems like its worth a shot.

[GTSailor]

Y'all definitely trust cadillac kid way way more than me. I'm a hack.

My chassis was very late 1998 and bus model 99. So not sure if I have a 98 or 99 Dt466E?

Interesting. the one i ordered has higher range 150-350. Me thinks that will not read correctly. looking at some "correct period" online dash cluster photos and your PN, 100-300 appears to be correct. Again... I'm a hack.

[cadillackid]

my book says the Ammeter is part number: 1690290C1



I dont know where thje shunt is located for the ammeter.. I didnt notice my ammeter having the large wires going through it directly.. in most instances there is a separate shunt for an ammeter .. a "sender" of sorts.. maybe its direct but I somehow dont think so as if the gauge was direct, then the bus would be inoperable with the cluster removed and mine still runs..



there are probabkly a lot of variances in these things..

I was wondering the same thing based on the wiring diagram it makes no sense. Like how is the current going through the meter? Maybe its a ratio of wire sizes??? 2ea #12 vs. 1 ea 20ga through meter?

.

So that shows a 100-300 range.

The one in the original post is a 150-350 range (and can be had much cheaper) I guess I need to find a 150-350 range sender from Navistar.... (or pony up more $$!!)

This is what i have on mine
1999 international 3800

I think you just put the + Positive side of the AMMeter to the junction the alternator connects to, and the - negative terminal of the AMMeter to the Positive on the Starter. According to that diagram you posted, it may take a large gauge wire, but I'm not experienced in this yet. I'm interested because I'm learning and want to add an AMMeter to mine as well. (Saved your diagram btw)

You may not have to actually put anything because the Harness already built in may take care of it all, which plugs into the Dash Gauge Cluster. It likely just needs your gauge installed, and the onboard chip on the Gauge Cluster should route it there because you're completing a circuit already in place. I'm just assuming here, never done it before. If it is the latter, then it uses a much smaller gauge wire used in the wiring harness, so like a 14 or 12 maybe.

I'd plug it into the bottom left of the gauge cluster as that's where I've seen others add them. It might be location specific so the gauge cluster main chip knows where to route Amperage info to. Try plugging it into the cluster and turn on the bus to see if it just works.

My bus is a 2001 with a build date of 2000. I have a 2000 series Allison. I also have a temp sensor "T" on the cooler line. Located on the right side.

You could just purchase an aftermarket gauge and be stand alone unless you really want the OEM gauge.
