Okay, I'm having an issue uploading pictures at the moment, but thought I'd get the writing out of the way first.
Have an 05 Avalanche with a 4L65 trans (per the label).
First I pulled the dash cover, then I marked the pillar to show where the gauge pod would be located. I then pulled the pillar.
I had to remove the vent/headlight control/4x4 control/cargo/fog light panel. It pulled out very easily, and of course I disconnected the four or five plugs in the back.
I wired the constant power in with my power lock system and put the switched in with the windshield wipers. I can easily get them their own circuits later if that's a problem, but didn't have the parts to do that at this time. Set the ground to a stud near the fuse box by the door.
Then came the fun part. I had to remove the front driveshaft to get at the driver's side of the transmission. Once it was out of the way I reached above the linkage box and removed (11MM wrench) the plug to the transmission pump pressure test port. I had parked the truck on an incline and no fluid leaked out. I wrapped the sensor with teflon tape and put it in the port. I quickly grounded the black wire (as per the directions) and routed the white one back up to the dash to the gauge.
I then used heatshrink on all the connections and mounted the pod on the pillar, and reinstalled the pillar. I then tested the gauge to make sure the wires were right before I covered the wires with the dash. Go figure, the gauge powered up fine, but was pegged at max. I checked the manual and it said that if the trans is cold and the needle reads maximum that the sensor is probably wired in backward. Well, I had put black to ground and white to the lead, but apparently my sensor came out of the factory on Friday. With a few snips and a couple more pieces of heatshrink it was indicating cold like it was supposed to.
I put the dash back together and before testing the gauge, installed my brake controller and my CB. I'm still trying to figure out where I'm going to mount my antenna (not many good mounting locations on the back of this vehicle), but the rest is good to go.
Went for a drive and with a mix of city and a few 65 mph blasts on the highway got the temp to about 150 which is considered normal for this transmission when it's not working very hard.
Total cost of gauge and pod, less than $50 with shipping.
Next modification, coil assist air bags. I need to get more heat shield before I start that one, the package comes with what is normally enough shielding, but I have dual exhaust which requires a little bit more to keep the bags from getting to hot.
