Re-doing a 1992 525i with A4S310 R transmission. When I got the car the trans program light was on. I took out the transmission and had it rebuilt. Installed it and the light is still on with the trans locked in 3rd gear. I drove it to the shop that rebuilt it and they pulled a code 45. Told me they thought I probably needed a new computer. I came home and did a little research and can only find that code 45 relates to band solenoid in the transmission. Am I on target with this one or is there something else I should know. Also there are no engine codes displayed.
