None. Just remember to unlock it when slowing down or you will stall (since once locked in... will not come out of overdrive until unlocked).

Will it still upshift, or do you have to already be in the gear you intend to stay in when you switch it on?

captain_stabbin · #10 05-22-2012, 04:16 PM

yes it will up shift

RAW · #11 05-22-2012, 04:20 PM

It will upshift, but it won't down shift. I have to unlock the T/C, turn O/D off on, then turn the T/C lock on again.

JBearSVT · #12 05-22-2012, 04:22 PM

Odd. Sounds like a PITA.

RAW · #13 05-22-2012, 05:29 PM

It can be, but I think the benefits outweigh the hassle.

JBearSVT · #14 05-22-2012, 05:31 PM

The more time I spend with this automatic, the more I think the same could be said for shifting a manual.
I mean, I've always felt that way, but this is a plow truck and there aren't enough hands as it is. My cars have always been manual.

can anyone direct me to this type of instruction for a 94? and are there any warnings i should be aware of?!!? am i going to hurt my trans in any way by doing this?
