Hello XXXXXX, Welcome to Justanswer!

How many miles are on the truck?

The "trans failsafe prog" simply means that the tranmission controller has detected a fault in the control system. There are several different faults that can cause the transmission to go into failsafe mode. Without knowing the fault code number I am limited in the information that I can give you.

It is possible that low voltage can cause the transmission to go into failsafe mode. You would also have some other symptoms if that was the case. The first thing that you would probably notice is the message display under the spoeedometer usually will blink when you have a low voltage issue caused by a bad alternator. You can also have random electrical malfunctions. I am pretty sure that if you are not having any other electrical issues like dimmed lights that you do not have a bad alternator.

I would simply ask the dealer to check the charging system. This is a simple test and should only cost around $40 for them to do.

$2500 does not seem out of line to replace a transfer case. If that is in fact the problem, their price is in line with what most places would charge.

Please let me know if there is anything else I can help you with

Thanks,

Todd
