I think I just blew my transmission

[Scott Curry]

So I was coming up the hill and it seemed have miss the shift from 1st to 2nd and it just kind of went flat on its face, when it came back down off the rev I tried to put it into drive and it wouldn't go it just started to rev really slowly and go into a gear, I lightly gassed it twice then it finally went in seems like it was driving okay but then came out of the store and now it's erratic all over the place shifting high than low, hard shifts, seemingly going out of gear and then going back in... Dear Lord what did I do!!!

 

[HerbieTheCar]

Okay, no offense dude, but how come you're always having these issues? I swear, there is always one person in a community that has more issues than any other member.

I also don't understand how you can miss a shift from first to second? Did it just bounce off the rev limiter?? The car didn't upshift for you?

 

[Scott Curry]

Yeah I don't know what my deal is but non-stop problems. I had it in sport, I was kind of coming around the corner and it just slipped when It went to go into second. it didn't feel like it bounced it just went into the red line and stayed there for a second it didn't hit a red live in there just kept going..

If it’s transmission related, there’s nothing we can do for you here. I didn’t even think it was possible to miss a shift in an automatic. I just figured you’d get shift denied until the speed/RPM returned to a safe place for the requested shift.

Goes to show I’m still ignorant to the ways automatic transmissions function. I’m stuck in my manual transmission ways.

Anyway, it sounds like a trip to the dealer is in order.

 

[Scott Curry]

I wonder if they will try to blame it on the wheel and tires and that it's lowered. so has nobody else accidentally got into the red line and had anything like this happen before?

 

[eflyguy]

I've never heard of anything like that, period. Been driving cars with paddle shifters for 6 years now.

 

[Scott Curry]

I thought theses things had a built-in safety that will shift. That's all that happened but then it went flat on its face right afterwards seems to drive fine for a few miles but now it's screwed up bad.

 

[nhcowboy28]

So over revving in first gear shouldn't cause that damage? I thought theses things had a built-in safety that will shift if you don't anyway. That's all that happened but then it went flat on its face right afterwards seems to drive fine for a few miles but now it's screwed up bad.

Disconnect battery for a bit. Then see if the “relearn” crap fixes anything.

 

[Scott Curry]

Yeah I thought about that, I'll give that a try

 

[Scott Curry]

Kind of a dumb question can you just disconnect the negative battery terminal, it looks like disconnecting the positive terminal will take about 30 minutes with all the crap they have on it

 

[MerlintheMad]

Disconnect either will disconnect the system from the battery. So do the easy one.

I really doubt that you "blew up" your transmission by over revving. There really is almost nothing we can do to break the trans; well, other than overloading it with too much HP on demand. But I think that would take a LOT of added on HP, like well over 500 HP. I'm speaking from the "expertise" of inculcating the wisdom of those who know. It has been said many times here that the Stinger is very safely underpowered so that Kia can give that 100K miles drivetrain warranty.

What I have experienced with the trans when I redline is that it upshifts every time. It won't even wait for me to use the paddle shifters in manual gate: if I hit the kickdown switch on a dig "NAV" just takes over all the shifting. Bang off the redline, shift bang off the redline, shift; then RPMs go up slower and no more redline, because I'm extra legal now and slowing down.

 

[Scott Curry]

Yeah I ended up just taking a couple bolts off and there is a clip that holds the hold the plastic plate down. It's disconnected sitting now so we will see

 

[MerlintheMad]

If your trans really is dead, I doubt it was anything you did. We've heard of a handful of transmissions going south on here. A local guy had his practically "explode" when several bolt heads sheered off where the driveshaft emerges; that wasn't anything he did wrong: it seems that in the factory they didn't even put thread lock on during assembly and the bolts worked loose. I don't recall the details of the couple or so of other transmission horror stories I have read, but none of them have been anything the driver did to cause them.

 

[Scott Curry]

Yeah I remember hearing about that one.

 

[SteveCo]

What other modifications did you make to the car - did you cut the harness brake signal wire ('brake snip'), to allow higher revs during launch mode?

 

[eflyguy]

It's usually simplest to just remove the negative cable at the chassis vs. the battery, but I've never gone into the battery compartment on my Stinger.

 

[Scott Curry]

No didn't do any of that just 20"s wheel tires lowered and Cat-Back exhaust

 

[Scott Curry]

Basics really.

 

[MerlintheMad]

I've never gone into the battery compartment on my Stinger.

Hey, I have done that! I had some notion of removing the battery to see the battery box from above (this was when I lost the drain plug a while back). It didn't take more than removing a strap to convince me that no way was I going to get that battery out of there; I put it back together and have never had the spare wheel out since.

 

[Scott Curry]

Do you think they will try to blame it on the wheels and tires.
