I have a 95 Yukon and the trannys been acting weird. Sometimes when I stop it stays in high gear. At first I thought it was slipping, but then I realized it never wound up the rpms, it would just take off really slow. It's like having a 5 speed and taking off in high gear w/o the studdering and jumping. It doesn't do it all the time either. Also sometimes it seems to shift hard both up and down. Anyone with some help?

It looks like your transmission is giving up, ONE OF THE BEST THING TO DO IS TO GET A SUPERCHIPS TUNER PART#2715 WILL MAKE YOUR TRANSMISSION LAST LONGER=more life

In addition, part number 2715 provides the ability to:
Adjust Shift Points
Adjust Shift Firmness
Eliminate Speed Limiter
Recalibrate Speedometer for Larger Tire Sizes
Recalibrate Speedometer for Gear Changes
Adjust Rev Limits
Choose from Three Available Performance Settings

or try an INTERCEPTOR Adjust Shift Firmness CLICK >>>>INTERCEPTOR (http://www.autotransinc.com/intercept.htm)

SUPERCHIPS $200-$350
INTERCEPTOR $130
THESE TWO OPTIONS ARE BETTER THEN WASTING $1,000-$1,500 ON TRANSMISSION REBUILT
