Tranny temp running a bit high.

From : miles

Q: i just had a tranny temp gauge installed and it seems to be running high. on the highway it ran steady at 195. then i hooked up my 4500lb trailer and got back on the highway. towed out of od at about 60mph. gauge climbed to 212. i am concerned that it will go considerably higher when i start pulling mountain grades. most have told me it should stay under 210 except for occasional spikes up hills etc. is 210-215 a normal driving temp truck is a 2001 qc 5.9l with factory auxillary cooler. i also installed a deep tranny pan that holds about 1 1/2 qts over stock. temp gauge sensor is installed in pan. that means the temp going to the cooler is even higher. any ideas .

sounds to me like you need to put a k&n filter in the trans. as per a previous thread the filter is causing a restriction building up heat in the process.. g denny i just had a tranny temp gauge installed and it seems to be running high. on the highway it ran steady at 195. then i hooked up my 4500lb trailer and got back on the highway. towed out of od at about 60mph. gauge climbed to 212. i am concerned that it will go considerably higher when i start pulling mountain grades. most have told me it should stay under 210 except for occasional spikes up hills etc. is 210-215 a normal driving temp truck is a 2001 qc 5.9l with factory auxillary cooler. i also installed a deep tranny pan that holds about 1 1/2 qts over stock. temp gauge sensor is installed in pan. that means the temp going to the cooler is even higher. any ideas .

james1549 wrote rule of thumb... trans temp can run 10% higher than engine temp. i wouldnt be concerned at this point. havent heard that. most of the shops around here say trannys should average below 200 with spikes above when pulling grades etc. i did a crude test. drove around until the gauge read 210. pulled over took the dipstick out and touched the tip. i was easily able to hold onto it. only felt a bit warm. if it were really 210 i would not have been able to do that. i then remembered i had an infrared thermometer i use with my gas rc trucks. it showed the dipstick to only be at 130. ill exchange the gauge/sender and see how a new set reads. the pan is full of oil cooled by the cooler. is that where the temperature sender is al .

value. the r4 software is the same software that is used to program the aic1 and psc1. a variety of editing tools ease the task of setting up an initial map and quickly fine tuning for optimum performance. features two three-dimensional map tables defined by absolute pressure and rpm avoids fault codes due to excess flow readings compatible with 2 and 4 stroke engines from 1 to 12 cylinders laptop adjustable laptop not included two modes for either direct output or signal modification can retard ignition timing by up to 20 degrees transient surge and battery reversal protection connection information this information and much more can be seen at www.splitsecond.com please refer to the installation instructions for a specific model for more information. this ftc-1 came off a 5.9 v8 dodge 2000 and older again contact split second to see if this will fit your application. this unit does not come with a laptop for configuring but does include the r4 software. this ftc-1 cost well over $680. new. any questions befroe asking please refer to www.splitsecond.com for references.  all information is there and is readily available for download in a pdf format. .
