Car started having blinking d light issue car has had vsa light triangle light and check engine light on since I got it. Went to drive one morning and d light was blinking car was hesitant to take off in d had to damn near floor throttle to get car to start moving. If in L car takes off just fine. I have cleaned out screens on solenoids on top side replaced both 3rd and 4th pressure switch behind drivers tire. Still having the issue. I believe car was throwing code for something With torque converter I can’t remember for sure. I’ve searched and couldn’t find anyone having the issue with the hesitation. Could it possible be one of the speed sensors or the. Neutral safety switch ? Any info would be greatly appreciated thanks

 

Forgot to mention I replaced the transmission filter as well.

 

Went back and look the codes car was throwing are the p2770 and p0974.

 

Just curious, were the pressure switches OEM?
If not, where did you purchase them from?

 

In theory, if it works fine in L but not D, that would most like be the transmission/gear position sensor. If the transmission itself had issues, L and D would behave the same....in theory.

 

I purchased off eBay. One was oem one was not

 

Do NOT buy these from eBay or Amazon...ask me how I know...

 

stop cheaping out and expecting good results

 

it might be the car's transmission downshifting when slowing down and it having rough engagement. when is the last time you serviced the transmission?
