reoccuring 637 memory code
Ive got a 1995 f150 4.9 4x4. I have had this random code on and off for almost a couple years now. I'm getting memory code 637 and 111 system pass. I have an older actron cp9145 that can scan and give live data. It says trans fluid temp above max voltage -40 indicated. According to my tool, my TOT was 103 degrees and my voltage was 2.3-2.4 during my test. SO, I'm wondering what is the cause of this code. Trans has about 20k miles on it. While my 4.9 is still great at 195k. I disconnected my battery 2 weeks ago and did the test yesterday. Seems to shift ok, but I have 3.55s with 33's on it now. (Regearing to 410s real soon) this gonna hurt my e4od? Fix? and thanks
