Engine/Transmission (1998.5 - 2002) Trany lock up fluctuation

[AGibson]

I recently installed RV275 injectors with an Edge EZ. My transmission is now fluctuating the lock up between 45-50 mph and 70-85. It locks up hard at first with the foot in the pedal but at about 1900 to 2200 RPM's it jumps in and out. The RPM's also jumps up about 100. The transmission has about 20K on it. The TC and valve body and other up grades came from Suncoast. I have also replaced the solenoids. The fluid level is good and serviced 5K before. Any suggestions?

Thanks!

Problem sollved

After talking to Joe at Suncoast I found out that the alternator can induce ac voltage if resistance is high enough. He said it is a common problem. High resistance can be caused from poor electrical connections and/or batteries going south. I disconnect the batteries, cleaned cable connection along with grounds to the block and frame, added conductive grease, and then reconnected. Next turn the ignition key to the run position and slowly depress the go pedal to the floor and then release. Turn the key to the off position and the job was done. I don't know if the codes have cleared because it is a 98. 5. I guess I can hit up an Auto Zone to check.
