1999 Ford Explorer. Transmission problem.

[pjreferee]

I have a 1999 Ford Explorer XLT V6 with 148k miles. Whenever I accelerate from 1st to 2nd the engine races until I let off the accelerator. After I let off the accelerator and allow the truck to get into the next gear, it will allow me to accelerate properly. I had the transmission flushed and the same thing keeps happening. Also, the O/D dashboard light starts flashing after the truck is driven for a few miles. I'm not sure if it is related. Any thoughts?

Welcome to this forum! I've moved your thread into the transmission section. It sounds like you have a broken band. Find out what the code numbers are, and adjust the bands.
