2000 grand cherokee Transmission question
Hi Guys,
I read that on Wikipedia :
1999 and 2000 model year WJ owners can have their 45RFE transmission's programming flashed to enable the extra gear as both transmissions are physically the same. The 42RE 4-speed automatic remained the transmission for the Inline 6 engine. It had slight changes from the previous model Grand Cherokee.
My english is not so good, but does that meen , it is possible to change the 4 speed into the 5 spedd by reprogramming it?
Thanks,
Norbert
