I wasnt paying attention the other day when I changed my tranny fluid, and I accidentally put in a quart to much... So today I went to drain the fluid, I was told I could disconnect the sending line to the cooler and start the truck and it would pump fluid out. So, thats what I did drained about a half a quart and now the truck wont go i an gear. Its an automatic trans, the E040, 97 OBS.

I think I may have just got air in there, what do you guys think? and if that is the problem would I have to drop the pan and drain all the fluid and refill it?

Thanks in advance.

 

Thats what is think happen you just got air in the tranmisson. Try letting it sit for a day and if that doesn't work you will have to drain it and refill it. I had to do that to an older chevy truck.

 

Got is solved guys, from what I understand there is a "front" and "rear" pump the front pump goes to the cooler lines, so when I drained it , and how I did it, I pulled fluid from the torque converter, So it did create a big air bubble. I let the truck run for about 15 min, then went through the gears, no gas-foot on the break, and stayed in each gear for about 45 seconds, went from N-D-2-1 put it back in drive and she's run'n strong
