my transmision has been slipping but sometimes runs fine .. I otice it burns a lot of fluid and I see a huge cloud of white smoke come from my tail pipe a times .. also it tends to idle funny and dont want to un rite ... I can put it in park and then start again and it drives fine for a little while then starts idleing funny again and even backfires some .... could this be my Transmission Modulator Valve?? i thought I was just loseing a lot of fluidfrom a leak so I put some stop leak/ no slip additive in it and it seems to hav gotten worse ..

The vacuum modulator would be a good place to start if it is burning white smoke and losing trans fluid. Unplug vacuum line at the modulator, if any trans fluid is present, replace the modulator. Be careful, there is a small rod int here that makes it work, be sure it is in there when you install the new one
