I posted last week asking about changing the trans fluid (It was changed 42k ago). Car has 103k on it now. Sometimes, when I push the gas pedal the car will "hesitate" before it starts responding. When it does respond, it gains speed and RPM's as if it never hesitated, meaning it's not revving up super high and kicking into high gear. This is an intermittent issue. Shifts normally, no slipping that I can see or feel. The hesitation usually happens when I'm slowing down for someone in front of me to turn therefore I'm asking for acceleration after having NOT come to a complete stop prior. Also sometimes will happen when I'm going to enter the freeway, so let's say I'm going 45 or so on the entrance ramp, then I all but put the pedal to the floor (we have short ramps) to join the traffic, and it's like HELLO? Car??? GOOOOO! I haven't really noticed it happening when I'm accelerating from a complete stop. More so when I'm asking for MORE acceleration after having slowed down some. Any thoughts on this?? I've ordered a scan tool that should be here today. I have NO check engine light on, no odd noises. It almost seems like lazy car LOL. Just this weird intermittent hesitation..Thanks!
It would be a good idea to scan for codes and live data. Have you checked for vacuum leaks? How old are your filters and spark plugs?
I just ordered my own scan tool which came yesterday..I just need to pick out an app to use it with for my phone. I haven't checked for anything thus far. Filters as far as engine air and oil? I keep up on them so they are normally fine. Oil every 5k and engine air once a year normally, if I feel it's too dirty lol. Spark plugs are original. Manual says to address that at 120k unless they act up of course, and I've not witnessed any misfires. Check engine light is NOT on, so I'll see what info this scan tool provides and go from there, and report back. 🙂
Make sure it has a fresh engine air cleaner in there.
Could be a lazy fuel pump (would have to put a pressure gauge on it)
Which engine do you have? The 4 cylinder is known for defective transmissions.
I always do.
I'll keep that in mind.
4 cyl 2ARFE-I've never heard that.
Torque Converter was replaced at 61k. I’m pulling C2121, U0100, U0101, U0151.
I don’t know if, these are old codes since I did in fact have the TC recall done in 2018, and SRS recall done in 2015 or 2016. Don’t know if they cleared the codes or not. I’ve never had the check engine light come on for anything. I cleared the codes and will see if they pop back up. I’m wondering if I have battery voltage issues going on?
I checked out your link and hope that’s not what I have going on, but I def identify with the “loss of power” analogy from one of the posts. That’s what’s happening intermittently. So am I looking at a whole new transmission? I’m unclear as to whether this is a torque converter issue or that and the entire rest of the transmission, issue.
the torque converter helps get the car moving until engine speed and wheel speed are matched up. But it's hard to say without doing some troubleshooting. An experienced transmission mechanic would have do some troubleshooting with a good tool , and watch input and output speeds to see what the transmission is doing.
Ugh. I’m not sure we have any of those in my area. Scares me to get near any of our transmission places. I’ll do some research and see who I can find.
