We went away from the standalone trans controller for 1996. 1996 was the first year for the integrated engine and trans controller on the RE family for all engines using the 42/44/46/47RE. Only the 4.0L had this standalone controller before 1996. You can change the shift schedule electronically through the software map or by changing the governor weights or by changing the shaft speed "read". To raise the shift point you would need to lighten up the primary (outer) governor weight. Trial and error but nothing that difficult. As for adapting this controller you need to determine the feeds to it and what form the signals are in. I would start with the Service Manual.
