rlbarkleyii Report post Posted August 13, 2015 I recently bought a ScanGuage D to monitor transmission temperatures, other system indicators, etc. Come to find out that the Allison 2000MH does not provide temperature to diagnostic port, therefore no temperature on ScanGuage! Short of dropping the pan and replacing same with aluminum cast pan with taps for temperature senders, anyone have any experience with installing a temp guage on this tranny?
