Not connecting to ECC
I have a 1990 F250 5.8l that I am trying to run a diagnostic check with SnapON Solus Pro scanner. I cannot connect to the ECC with the scanner. The scanner is new and I am connected to the correct spot. I cleaned the connections. What would cause this?

I got it to work. I am getting code 62 coverter clutch slippage. Would this cause my hard 2to3 and 3to4 shift when hot. What should i check next? This is the original trans with 81k miles 2nd owner with no towing or junk in the pan.

Here's some info I found on the web. Looks like water can get into the transmission range sensor and mess it up, along with the wiring.

Yes. When the PCM detects the converter slip, it goes into "fail'safe mode" that maximizes EPC pressure. The high EPC pressure in turn causes the hard application of of the clutches during shifting.
