I recently changed out my A/C compressor. After I finished my transmission makes like a clunk when it shifts gears. I'm getting a IAT (Intake Air Temp) Sensor code, saying that it could be a bad sensor, faulty wire, or bad connection. Was wondering if anyone had any insight into this?

Is the sensor still plugged in properly? it could have been knocked out during the A/C work. Can't really say about the trans problem, maybe the extra load ( from the A/C compressor ) is effecting the shifting. Best of Luck!

IAT is intake air temp sensor/plugs into air snorkle right after air filter bofore getting to throttle body/has tendency for broken wire right at sensor connector.

I had this problem of shifting hard after i worked on the car. I left the vacuum hose off the air intake /filter housing. I reattached it and the shifdting returned to normal.
