Since the transmision acted up while testing the Maverick at the drag strip, its getting a temperature gauge. My brother in Arizona added a 1.25" section and two 1/8" NPT bungs -- one for the temp sensor and another for a drain plug -- to a C4 pan. I know pans with bungs are available but I'd rather have this one made by my brother. He's getting up there and isn't as steady anymore so welds are not up to his standards but they're a whole lot better than mine would be. Sensor is for an AutoMeter Transmission Temp Gauge that's mounted but not wired up yet. Empty hole is for a Air/Fuel gauge some day. LEDs indicate when AC compressor is running, radiator fan is running on low speed, and another not quite visible one indicates fan on hi speed. The LEDs will eventually get mounted in the gauge panels. Have another 3-way for oil, water temp, and volts backordered at Summit. Its a lot cooler in here posting than it would be in the garage working on this stuff.
Like the LED for compressor. I got one for my fan but none for compressor. Have to make that a to-do. How the trans workin now?
The fan controller turns on the low speed fan if the compressor is on. Having an indicator light for the compressor and another for the low speed lets me know if the low speed is on because of radiator temp or because the compressor is running. Transmission has been perfect EXCEPT at the drag strip.
Very Nice! I have a temp gauge on my pickup, which is handy when I'm towing, I never thought of adding one to my Maverick.
What temp should the trans be running at? Right up the middle around 180? There is no red "danger" area on your gauge.
the C4 should run at 170F maximum for the longest life. The minimum temp should be high enough to get any condensation out of the oil so around 120F is minimum.
Trans Cooler The gauge said the trans fluid in the pan was 210* while cruising at 70-75 MPG on a 90* day so a cooler was added to the list of to-dos. Challenge was finding a place to mount one. Something that happened on a hot day this summer made me want to avoid putting it in front of the condenser and radiator. With a front (decorative) license plate installed, and blocking a good percentage of the air flow into the radiator, the fan came on low speed while going down the road at 40-50 MPH following a big trailer. The front plate has been removed and I'd like to avoid any other things blocking air to the radiator. This cooler http://www.summitracing.com/parts/BMM-70268/ is only 3/4" thick and fits begind the grill on the side with 1-2" of space behind it. Not an ideal spot for air flow but I'm hoping it'll keep the trans temp down. The lower edge of the cooler is mounted to the splash pan and the top is held off the radiator support by 1/4x2 1/2" bolts. Feels good and solid. Hope it does the job.
Can you put a fan on it? It looks like there wouldnt be good air flow with the radiator support behind it. That just came to mind when looking at it.
No room for a fan. There is 1-2" of space between the cooler and radiator support so some air will get thru it. If its not enough I'll remove some of the radiator support to provide more air flow. I'd like to get more air into the engine compartment anyway -- it gets really hot in there.
