six speed 1 to 4
I'm new to this so forgive me if I miss something. I've got a new 2013 grand sport with a six speed transmission. It's a little frustrating trying and shift from 1st to 2nd and it will only go into 4th. Anybody know how to bybass the 1 to 4 shift deal. I understand it's something they designed in to improve economy. Thanks Rick

2013 Owner's Manual, pages 5-21 to 5-22.
One-to-Four Shift Light
(Manual Transmission)
When this light comes on, the
vehicle can only be shifted from
1 (First) to 4 (Fourth) instead of
1 (First) to 2 (Second).
The shift must be completed into
4 (Fourth) to turn off this feature.
This helps the vehicle get the best
possible fuel economy.
After shifting to 4 (Fourth), the
vehicle can be downshifted to a
lower gear.
Notice: Forcing the shift lever
into any gear except 4 (Fourth)
when the 1 TO 4 SHIFT light
comes on may damage the
transmission. Shift only from
1 (First) to 4 (Fourth) when the
light comes on.
This light comes on when:
. The engine coolant temperature
is higher than 76°C (169°F).
. The vehicle is going 24 to
31 km/h (15 to 19 mph).
. The vehicle is at 21 percent
throttle or less.

Bill where would I get a shift kit? This 1 to 4 deal is killing me. Happened to me twice yesterday for no real reason. Everything else is good to go on the car. I love it! Thanks for your help. Rick

Just give it a little more gas and you might not need it.
