Super Sweet Auto Trans Issue

Recommended Posts

So I was coming off the highway and went to make a right turn hit the peddle and it decided to act like it was in neutral.

Shifted into 1st had acceleration 

Shift into 2nd still going

Shift into D it would carry on

Come to a stop had to repeat 

R works fine as well.

(Radiator is bypassed from transcooler, and trans fluid does not smell burnt)

Any insight to what could be causing this is greatly appreciated

Does the issue go away after it cools down and then starts again after warming up?

I can get it up to 20mph "manually shifting" and switch to D and all shifts fine

Seems to only "act up" from a dead stop

Mine is doing something similar to yours.. instead of acting like neutral mine slips and bogs and transfers almost no power then all the sudden it let’s go and all is normal until stopped completely again.

 

Does yours act like complete neutral when it messes up or is there any forward transmission at all?

At dead halt, and shifted to D very little power transfer

Shift to 1 or 2 good to go

Once she's in 3rd everything works normal including OD 

At highway speeds I can let off then accel and all works as it should

Sound like yours?

Well I don’t know about the shifting into 1 or 2 because I didn’t try it.

So when you are at a halt and there is no power being transferred, when you hit the gas does the engine rev and the RPM fall slowly just like you were in neutral? Or do the RPM rise to a certain point, around 1500-2500 RPM and fall very quickly, just like they would if you were in D and pressed the gas with the brakes pressed?

From N to D it doesnt even register at dead halt 

Stays around 800ish 

 

In D it will act like N

 

R, 1, and 2 will drop rpms 

No hard shifts

No clunks

Operates like it normally would

Weird. Makes me wonder if it might have an electrical issue. Have you run codes on it?

My scanner either doesnt pull trans codes or didnt have any at the time i scanned

Everyone except one guy who worked at a dealer says electrical

And it makes sense to me

I agree with Slart. It sounds like a solenoid isn’t doing its job.
