so silver whats up with all the student parking passes on your windshield.. is it mandatory for your HS to have 4 passes or you just collecting them threw your years

 

the bottom two are registration and inspection stickers. then the two with the viking logo was my hs sticker just havent taken them off yet. my college one is on the bottom right side of the windshield

 

great write up! its a fun project i had one on my old jeep. now looking at this makes me want to put one on my truck. one question tho, what color is the back light of the gauge?

 

ill get a pic of it tonight. i tried to take one last night but the flash kept coming on and you couldnt tell the gauge was on. The numbers light up white/silverish lol and the tachs alternate between that color and gold/yellow and the needle stays the same color just lit up. but i will get a pic of it tonight

 

Thanks

 

good job young grasshopper your learnin!!

 

thanks wise owl lol

 

i justhave one question, what is the normal operating temp of the tranny? when is it too high??

 

I stole this from another forum..... I have not accurately tracked ambient temp vs trans fluid temp in my own truck, but these numbers look reasonable.

Trans fluid temp depends on where the temp is measured...output to cooler will be highest; return from cooler or pan is cooler. My tranny temp sensor is in the pan, which is probably the most accurate, most meaningful, and least subject to "spikes".. What I've seen over the past year (at highway speed):

Non towing: temp will be about 40 degrees over air temp (e.g. air temp of 70 means trans temp of about 110; air temp of 90 means trans temp of about 130. Temp measured with torque converter clutch locked.

Towing: Temp about 60 degrees over air temp on level roads (e.g. air temp of 90 means trans temp of 150). On grades where the engine is working pretty hard but the torque converter clutch does NOT unlock, the trans temp will climb to about 75 degrees over air (e.g. air temp of 90 means trans temp of 165). On long hard climbs with the TC clutch unlocked (engine at WOT in 2nd gear), the trans temp will steadily climb well above these numbers. The highest trans temp I've seen so far was 195 degrees at the crest of a 5 mile long, 6% grade with 95 degree temps. I've seen temps of 180 to 185 multiple times after 8 to 10 mile climbs on 7% grades where the air temp was more like 60 degrees.




Trans fluid starts to oxidize above 170°F (might be for conventional only., Our 3rd gen trucks come from the factory with synthetic so I'm not sure of that number)

Temp of FLUID vs Life expectency of FLUID
--------------
175°F 100,000 miles
195°F 50,000 miles
212°F 25,000 miles
235°F 12,000 miles
255°F 6,250 miles
275°F 3,000 miles
295°F 1,500 miles
315°F 750 miles
335°F 325 miles
355°F 160 miles
375°F 80 miles
390°F 40 miles
415°F Less than 30 minutes

Above 300°F, the metals inside the transmission will warp and distort in varying degrees depending on the severity of overheat

I'm not sure what to make of the statement below that most everybody has heard before. I don't believe that if you push your trans temp to 195 for 5 minutes ONCE in it's lifetime that all of the sudden you have cut it' s life expectancy in half. I assume that it applies to running at the temp constantly.

"In fact, for every 20°F temperature increase above 175°F, transmission life is cut in half."

 

drove it around today and it was around 150-170 degrees for the most part
