TWO very simple ways to fix the reverse low range transfer case breakage problem
1--- Drive the truck like YOU own it and YOU have to pay to fix it, NOT like if you break it, someone else (tax payer) will fix it.
2--- Disconnect the automatic front wheel engagment when going into low.
It eaiser to put a lockout for low reverse and stickers saying "DO NOT PUT INTO REVERSE LOW" then to train young GI truck driver how to drive a big truck.
The problem is that the truck goes from 2 axle drive in high to 3 axle drive in low, the young GI truck driver thinks that there is only ONE throttle postion most of the time and that is on the floor boards, the truck is having trouble in high so he drops to low, since it is now in low, it will need ALL the power it can get, so NOW all 3 axles are pulling with traction and with a lot of instant horsepower, SOMETHING HAS TO GIVE, the transfer case TAKES THE HIT.
Bet I could break something putting any 5t into low forward/reverse, crank the rpms up and dump the clutch, the ONLY difference here between the 900s and the older 5ts is the when starting out with a clutch you have to eze into it on the throttle, where a automatic you can just floor it and go.
