I am begining to think that these GM service techs are not all versed in the products that they sell. Case in point: I am looking to have the transmission fluid changed in my truck. Currently I tow a fifth wheel and want to make sure that I keep up the maintenance with the Allison. For insurance sake, I order two 2.5 gallons of Amsoil synthetic ATF dexron III compatible fluid for the change.
After I recieved my order from Amsoil, I call my dealer and mention to him that I would like to have the fluid changed but I will be supplying the Allison filter and fluid for this preventive maintenance procedure. No problem. Then I mention the forbidden word "Synthetic" ATF fluid. They schedule the appointment for October 17th. No problem.
Later that day I get this phone call from a guy named "Paul" indicating that they have checked the GM service manuals and that the transmission requires only Dexron III ATF fluid. They said not to buy the synthetic fluid as they do not want to use it.
Well this morning I call the dealer to find out what heck is going on. I mentioned that the ATF fluid is Dexron III compatible and suitable for use in the transmission. I also mention that Allison recommends TransD which is also a synthetic oil for the transmission.
"Well you will have to bring in the container to let our mechanic look at it and make sure it is suitable for use in the transmission" barks the dealer. I think to myself, "What am I stupid or something?"
I am begining to wonder if these fellas have ever changed the fluid in one of these transmissions. Can anyone enlighten me on this?
BTW they will be replacing my two piece drive shaft to the infamous flag pole type to cure the launch shudder. They also will be reflashing the computer for the lopey idle and Allison shifting.
