Please look at my TORQUE APP screen shot.

[TURNz]

I finally have a vehicle that the Torque App can read Transmission Temps. Of course I don't know what temp is considered good and at what point its too hot.

I had been driving for about 40 minutes, mostly non-stop, averaging 40mph or so. Ambient temp was 56F according to my rearview mirror readout.

COOLANT TEMP: 188.6F. I assume the t-stat is 195, so that seems normal.

TRANS TEMP: 134.6F. I've pretty much been seeing mid 130s.

INTAKE TEMP: 57.2F. This is strange to me. Only 2 degrees above ambient. In my DODGE RAM, even when the ambient is in the 40s, the intake temp is well above. The Ram sensor is in the manifold. I guess the Chevy is more in the actual intake tube?

SPEED OBD: 59.7mph. One readout that I didn;t have on this screen is SPEED GPS. It actually reads almost exactly 5mph higher than OBD.






What other readouts do you all find useful?

Tranny looks good, not that high. Anything above 180-200 for extended periods would be concern though.

I can assume that you are in a northern state, judging by your posted ambient temp of 56. I'd say the coolant and trans temps are fine. The intake temp shouldn't be much more than ambient while moving. This indicates that the seal from your air filter box to the fender is still in good shape. This is why I, and plenty others consider the stock intake to be a "cold air intake" and all that can be improved on performance-wise is a smooth intake tube to get rid of the muffler chambers. It's just not as pretty as those $300 CAI kits. Since you called your truck a "Dodge Ram", I'd assume it's a pre-2010. I tried to Google some pics of the stock air intake assembly on an '09, but found none that I could see from where it drew in air on the V6 or V8 models. But, the Dodge Ram has been around since 1981 and you may have an older generation from somewhere in that 28-year span and it may have a crappy intake design. As far as the IAT sensor, it is in the intake tube on a GM. I don't see the logic in placing the IAT sensor in the intake manifold since it could be affected by engine heat.

As far as the speedometer reading slower than the GPS reading, I'm gonna guess, again- assuming you're in a northern state that gets snow and you may have a 4x4, that you have larger tires than the stock size. This will make your speedometer read slower than your actual speed. I've always found GPS speeds to be around 1MPH slower than actual speed. I've always chalked the inaccuracy up to the delay of signal from the satellite to the Nav device. On a phone, I don't know. Those triangulate the data from cellphone towers and not by an actual GPS in space.

My Ram is a 98 SS/T. It has the 360 Magnum with the "Kegger" intake manifold. A popular mod is to plug the IAT port and lengthen the wires and install it in the TUBE. I haven't done that yet. I'm waiting to install a modded kegger. What would I call a post 2010 Ram? I realize RAM is it's own division now, but I assume I'd still call it a Dodge.

I am in PA. I'm not sure if the tires are oversized. I've only had the truck 4 days. I do know it has a small lift, so the tires are probably taller too.

At 6am it was 56F, now at almost noon, it's 76F.

Post 2010s are just called ram trucks. No dodge anymore. I still call them dodges though haha.

I was replying under my best assumptions from reading the OP's post using the limited info provided. I'm thinking we should make it mandatory to include the basic (and obviously necessary) vehicle info in our sigs. Actually, I'm gonna go suggest this in that recent thread on this...

Josh, it sounds like the IAT sensor being in the IM is a known problem since there is a popular mod to relocate it to the tube (which makes better sense). Anyway, that's for a Dodge forum. Everything looks fine on your temps, etc. Check your tire size. If they're larger than the size outlined on your door sticker, then that'll explain the speedometer inaccuracy. Just keep it in mind when driving so you're not doing 15 MPH over the speed limit when you think you're doing 10 over.

I only get concerned when mine goes above 200. Pulling a 2,000lb trailer over an 11,000' pass in July or August the highest I've ever seen is about 209.

Honestly if you don't tow or haul heavy loads you probably don't need to worry about trans temp.

Actually, all modern cellphones have an actual GPS chip in them, and work like any nav GPS or handheld GPS. The only thing they do different is they get some help speeding up the initial locking in on the GPS sats with some data from the cell towers.

Try a GPS speedometer with your phone in airplane mode to see the difference.

We do have a large Pop-up camper that my wife's Suburban usually tows, but I may use the Tahoe occasionally to pull it.

It didn't even register with me what dub said about GPS. Yes, phones absolutely have real GPS. They had GPS since 2003 at least. Actually there was a federal law passed that required all phones have that after a certain year. It was after someone was abducted and left in the truck of a car with their phone. 911 couldn't find them because the tower locating wasn't very good. It was something like 6 hours.

I also have the tire size answered.

Door says P265/70R16 (30.6" tall)

Tires are LT295/70R17 (33.25" tall)
