Last night, I was coaxed into doing a "little" burn out when I had left from picking up my girlfriends' daughter. After about 80 ft. and much smoke and two nice stripes , .I let off the gas and rolled out the rest of the way to the stop sign. I shifted from 1st into OD. When I left from the stop sign, I no longer had 1st gear. I can get first gear if the selector is in 1st, but that is the only way! To make things worse, I turned onto I-43 southbound and accelerated "quickly" and I had no OD . I had to drive from Greenbay to Germantown( just north of Milwuakee) in third or Drive. It was a long and very loud ride with the engine turning 3200 rpm all the way!!!
I'll break out the GM service manual and begin looking but I am open to suggestions... any help is appreciated.
A little info on setup:
Stock 10-bolt 3.23 gears
stock 4l60e w/ shift kit
Edge racing converter 3400 rpm stall
tranny cooler
PCM for less tune

 

mine is doing the same thing shut your car off and restart it and all the gears are back not sure what problem is but i want to know

 

I wish..... I am the unluckiest person in the world, well, when it comes to good luck at least. Unfortunately mine wasn't that simple.... I 'll get into it tomorrow

 

Well, I got it fixed, sort of. Like you said turn the car off, but when I initially did that, it did not work. I changed the fluid and filter and it was fine. The fluid seemed to be good. It was still more pink than burnt. Not sure what happened, but I will try to get some sort of an answer to this.
