BRING DA AMBALAMPS
On my way back from Texas Diesel Nationals yesterday I noticed my trans temp gauge slowy climbing up past 180, then 210, then 230, then pegged the 260. After about a minute, it started jumping around all over the place. My temp gauge on the dash never moved out of the normal range. It's done this once before after I got my EGR delete on. I took the sender out, cleaned it up and checked the connections and everything looked good. It's worked fine until yesterday. Checked the ground going to the brain box and it seemed fine, especially since my other gauges were working fine. Do I have a gremlin in this thing or is there anything else I should look at?
