Transmission Programming

Hello. I own a Winnebago Grand Tour Vectra 1997 With a 250 HP Cat Engine and a Freightliner chassis Model: WKM35WQ. I tow a Jeep Wranglar X Unlimited with a Blue Ox package. From many peoples reviews on my other topic it seems my Transmission is not programmed for towing it. So where can I go to get my transmission or something inside the engine to realize that it needs to adjust gears according to a jeep also. It's only programmed to move the RV not the jeep with it. I kinda figured this out because I went to Catapillar and they brought a computer out with wires in the dash and some going all the way back to the engine, and he made me drive and said everything checked out, and my transmission was fine but I also realized that it was doing fine when usually going up a grade is bad. So I left all good but then it happened again when towing my jeep and going up a grade my RV won't gear down my RPMS drop somewhat and then my speed will drop a huge amount usually from 70 to 40 but I fix this by manually dropping the gears from 5th or 6th down to the 4th or 3rd gear and then going up a hill is great I can go up a hill around 50 or 60 sometimes. But my question is, is my transmission failing ir does it need to be calibrated to tow a jeep?

your posts are confusing and hard to believe.You said in the last section your rpm @60MPH stayed at 2000 but then your speed dropped to 40MPH and it was till @2000 now your saying your RPM will drop somewhat when the speed drops I seriously can not see this little 250HP unit going up a hill towing in 4th gear at 60 MPH
I believe you are expecting more than what this overloaded underpowered unit will do.
