got me a 99 2wd w/a 3.9 auto, and the dam thing acts like it slipps out of OD when i take my foot of the gas some times....step on the gas and you can feel it going back into OD after a hesatation, this is not a normal shift down, just started acting like this in the last few mounths and I have had her for a year. first one for me with the push buten OD. she has 110K there about, could it be just fluid break down? she had 68K when i got her, and not throwing any codes on the reader.

 

mine seems to drop down btwn 40-45 again almost like an exta gear and acts like your describing, but mine is just the torque converter locking and unlocking as i let on and off the gas(i think)

 

is your tranny fluid full?

 

yes fluid is full, and other than the o2 senser she's not throwing any coads

 

change the fluid, not flush, change the fluid
