So I finally got the Elantra back on the road. It was driving fine for the past few days. When I left for work today at 1:00pm, I noticed it was acting rather strange. When I push the acceleration pedal down to 50%, it will take awhile for the RPM's to build then it will finally go. It will get to about 4,000rpm and then shift alittle hard. During highway cruising at 60-70mph is will be fine. I checked the fluid and its fine, no burnt smell and at the right level. Thoughts?

 

Turbo off of it now? If so, maybe it misses it. lmao.gif

Was it especially cold today or anything like that?

 

lol turbo withdrawal.

is this an auto?

 

This is an Automatic. It was not cold at all, mid forties this morning.

 

when it shifts hard is there any cel? or any at all?

 

There is a CEL for the primary oxygen sensor. I believe Advance Auto sold me the wrong one.

 

in my sisters elantra it used to shift hard and throw a couple cels. if yours doesnt have any im not sure what it could be. how many miles on it?

 

I tried several aftermarket O2 sensors, but they don't work at all.

Buy the OEM O2 sensor from the dealer.



I think you might want to change your tranny oil.

 

Just over 97k. I'm going to get a filter and change the tranny fluid tomorrow. Also, I'm going to get the oxygen sensor from the Tiburon and try that.

Found my problem. Freewheeling stator in the torque convertor. Time for a new transmission.

 

>.< Meh well, it put with 12psi for a while, twas a good one.
