Automatic Frs stalling
 

Hey guys I recently discovered this issue when I was on my way home from work and I was coming up to a red light I was going about 45 50 and I had to stop suddenly because of the person in front of me and when I did this the rpms dropped very low around 1kish the engine started to shake and the car shut off.the car is tuned with a perrin Cai, uel header and perrin 2.5" cat back. Any ideas? It does not always happen when I'm coming to a stop only when I need to suddenly stop.

Poor tune :iono:

It's shivs ots tunes that were checked up on by steve

Do you have the regular Perrin intake or the big MAF one?

I have a AT. I can pull a 180 backing out of my driveway. About 1/4 the time my car stalls. My car is stock. I know this doesn't help, but I sympathize with you.

Regular one

But the thing is I'm having no idle issues only when I'm coming to a stand still

I've had this exact same issue happen to me, for over a year now. I have an ECUTek tune from one of the best 86 tuners on the platform. I've had him review logs when I stall and my engine is performing perfectly.

To me, sometimes it feels like it's (torque converter) having trouble disengaging from something fast enough.

Using ECUTek I believe all my ECU software is up to date, but I'll have to double check the transmission ECU.

Only a problem when at a standstill. Track/Canyon/Highway/Continuous driving has shown no issues, just when I come to a stop, more pronounced with sudden stops.

So basically everything is fine? I just want to Make sure. I can deal with being cautious on breaking so hard just want to make sure I won't cause any damage or have caused any damage

I mean, I'm sick of it, it's so annoying. I've learned the drive accordingly around it. I still need to remove my setrab cooler from the line, because I suspect the fluid may not be getting up to proper viscosity.

I didn't know autos can stall...

Learn something new every day :)

They can :lol: if say you do a j turn in a parking lot incorrectly, or if there's an idle air control valve problem, or bad maf. Most of the time it's an engine problem not a trans issue.

Well, now @soulreapersteve , usually it's the engine that stalls ........ automatic transmissions very rarely stall .... and when they do, the inside has turned to mush .........:D

That's the reason why some call automatic transmissions "slush boxes" ..... because they sometimes turn to mush.

Sorry, ......... it's a real slow day down here in Puyallup ....... :sigh:
