Hello guys! I bought my 07 base around 5 years ago with 84k ,now is at 115k , around 90k I did the tranny pressure switches and a tranny flush I never had Any issue with the tranny and right now I don't know if it tranny related, like 1 year ago I noticed the blinking d on the dashboard ,didn't feel anything wrong ,use the scanner and it was the tranny gear switch ,bought it but never installed, and never had the issue again. Like 6 months ago I went in a 20 - 30 miles highway trip, when I exit the highway I stop at a light and when it was time to hit the gas the car was moving really slow like it doesn't want to accelerated right in front was a gas station so I pull into put the car in parking and then in drive and it was fine , drove the whole day and never had any issue again , so I was thinking that it was my imagination. But now my wife told me that it happened to her last week and yesterday we went into another 30 miles highway trip and time after I exit the highway and was at a light it happened again , the car start moving really slow I hit the gas and the revs went to like to 2.5 and the car was still moving really slow I press the brake and then the gas and it was fine! Drove back with no issues , one thing I need to mention is that my wife told me that when it happened the radio went mute and yesterday she point that out too, I didn't noticed because it was only for like 5 seconds, the scanner shows no CODES. so I don't know what to do.
Sorry for the long post and thanks for any help in advance.

 

This thread appears to be similar to yours - blinking D light, no codes https://acurazine.com/forums/3g-tl-p...ashing-848418/

 

Thanks for the reply! D is not blinking, it did it once and I pull the code and it was the range sensor but I never installed the new one and that was a year ago and never happened again. The issue no is that couple of times in the last week or so, after stop at a light release the brake the car start moving but really slow the RPM went to like 25 when I was hitting the gas but the car was moving slow then I press the brake and then the gas again and it was fine. No check engine,no nothing .

 

The fact that it is really intermittent and immediate fail and pass type behavior, I would vote for range switch. Otherwise, what is the fluid condition looking like now? If it is really slipping, the fluid should be quite obvious.

 

Tranny Fluid looks fine, is clear orange/red. I did change the range/ neutral switch today it was a pain to to but it's done, never had any issue with the tranny slipping. It's bad when you don't have a check engine code , because you don't know what it is, hopping that never happen again.

 

check your battery connections and make sure there is not excessive buildup. Also check the power wires from battery to fusebox and alternator! Loose power wires can cause all sorts of electrical gremlins.

 

Thanks! Battery is like 6 Months old , no corrosion , but going to check everything else.
