Transmission Flush

2good2Btru · Jan 10, 2012

Took my truck for a tranny flush on Wednesday. It has 33k miles on it. Has been tuned since 2k. Tranny was perfect, no complaints. Picked it up on Saturday, and its just shifting like crazy and if i lightly step on it about 60mph, the converter unlocks and will not lock up again after I let go of the pedal.
Was throwing two codes, don't remember the exact numbers but one said "Shift Solenoid or Stuck Off" and the other one said "Transmission Friction".

What the hell happened, it was working perfect?

Thanks

It's a sticky solenoid. What kind of fluid was used? The wrong fluid will make solenoids stick.

This is why I am going to pull the pan and change the filter. Flushes scare me.

I don't know and didn't think in asking? I would think they would know which one to use but who knows.

Did you take it to a Ford dealer or another shop?

Very good chance they put the wrong fluid in it.

They told me they put the same stuff that it had in it. What is the correct fluid and I will talk to the guy first thing in the morning.

First thing I would do is ask them, "well what did it have in it"?

They cant look at the fluid and tell what it is.

They should have used Mercon SP or the newer LV. You can mix the two.

If they used Mercon V=BAD.

Again, find out what exact fluid they used before you divulge any information of what should be used.
