Hi,
I just installed my Mag-Hytec deep pan (I don't know who developed the transmission oil pan without a drain plug but I would love to kill them ) and I can finally hookup my transmission temp gauge. After a run down the freeway I noticed the trans was running about 130 degrees (72 degrees outside temp) with no load. Is this about right? Hot hot can it run before I should worry? How many qts of fluid should I have put back in? The Dodge dealer said 5 qts but it looks like I drained 6+ qts.

Thanks

Javamann,

I've got the Mag-Hytec pan, and running solo I also run about 130 degrees on my gauge. In the summer, driving in stop and go traffic, the temp has gotten up to 190 degrees. While towing the fiver, it usually rides at about 165 degrees or so. When the temp gets up over 220 degrees you have to start worrying about shortening the life of your fluid (and transmission) if the temp stays there for any length of time. If the temp reaches 270 degrees, you are cooking things pretty good.

Hope that this helps some.

Dave from Goerand Bros. Transmission told me that the temperature in the hot line can get to over 250. He said 270 is when you want to pull over and idle it back down. In the pan, I suppose that would be around 230 degrees. But your gauge should be in the hot line, anyway.

Listed below I have put a temperature "chart" down for
you. Remember, these temperatures are "guidelines" only
for the best operation/life of the transmission.

Temperature: Effects of the Temperature:

175 Degrees Optimal heat level for oils, seals
clutches and plates.

220 Degrees Oil viscosity begins to break down.

240 Degrees Varnish begins to form.

295 Degrees Plates can begin to slip.

315 Degrees Seals and clutches burn out.

I've got mine in the hot line and the highest I see it normally is maybe 205 sitting in traffic. Otherwise it's around 150-170.

4-8 qts depending on how long it sits before or during draining.

If your temp probe is in the pan it isn't accurate, your oil may be seeing temps over 100° higher than what the gauge is reading.

FYI, I have 2, 93s, one sender is in the pan and in the cold months it seems like it rarely moves. The guage starts at 120 I think, and in summer it will hold out at 140 150 unless towing heavy.Both have super coolers, at one point, pulling and going real slow up a dirt road it got up to past 250 a little. I would have hated to see what the real temp was from the converter, It would have been 300+ im sure. The other is in the hot line out of the converter. It will run 175 min and has gone to 215 unloaded empty pulling a small grade. There are big fluctuations while driving. It almost makes me wanna put it in the pan. I guess I really dont wanna see, its scary when it climbs up.

Yup, in the pan your getting the fluid after it has been cooled. You should put a T in and monitor the fluid going to the cooler. Better yet use both, with a switch, and periodically check the pan temp to makes sure the cooler is doing it's job.
