Hopefully I get a little more input this time around.
I posted the problem almost a year ago and got zero response, still having trans glitches and am looking for a little advice.

The problem I posted a while back :
This seems to ONLY happen in the winter, it has only maybe once done it this spring/summer/fall BUT it does shift hard/shudder between 1st and 2nd 85% of the time. My problem is that the problem is intermittent, I still have a powertrain warranty and want to get it fixed before it goes out and/or my warranty expires but I am afraid they will not be able to recreate the problem and just take my money or even if they do find it shifting hard between 1 and 2 they will just shrug it off. If they look at it and find nothing its $150 to me which I really dont want to spend ATM and the problem is still there, if they do fix it, its only $100 and my truck is fixed anybody have any suggestions? It is going in regardless to have the pinion seal replaced, just not sure I want to fork up more dough to have them "look" at my trans. and find nothing.

 

yhea, get it fixed

 

Have the ATF flushed/changed and replace the filter. Make sure to use ONLY Mercon V if it calls for Mercon V.

 

Bummer, not the answer I was looking for warranty doesn't cover a flush. Do the symptoms sound like dirty/old fluid and filter or is that just a temporary fix to cover up the real problem? I don't want to flush and fill it to prolong its life till just outside of the warranty then have it shlt on me.

 

Well, I brought my truck in to have the pinion and diff cover seals replaced and told them to take it for a spin just to see if they though something was wrong with the transmission once they got it done. Sure enough they felt the same thing I did and are taking it apart today. It better be covered by the warranty....hopefully a new transmission? Is it common to have transmission problems around 60k?

 

Please report you findings. I had the exact same problem, feels like hitting a pothole or you just got hit form behind.

I did a trany flush with new filter and it fixed it, although I would like to know what was happening.

 

Hopefully they will be calling me today with an update and I will post once I get more info. They where originally trying to sell me into a flush and filter but wanted $150+ for it. I didn't want to do that to "relieve" the problem for a while only to have my tranny go after the warranty expired.
But yeah the jolt on the highway was pretty violent, felt like the brakes just lock up quick then let go and the shudder between 2nd and 3rd was pretty gross too.

 

Just talked to the Stealership and they said they had to replace a solenoid in the trans...problem solved. Ill be glad to have my truck back this Taurus sucks. They also said I should think about front brakes, if I want they can do it while its in there. $300 and some change but they have a $25 mail in rebate. Ummm no Ill just do that myself thanks.

 

Which solenoid was it?

Rich

 

She didn't say, I will find out when I pick it up. I am unfamiliar with the specifics of the transmission, how many are there?

 

Prolly the overdrive or the LTC solenoid. That happened to the wife's car. Overdrive solenoid went out, started randomly dropping out of OD and eventually would ever hit OD. Tried the fluid and filter change, then took it to the dealership under warranty.

 

I am pretty sure it was not the OD solenoid, last winter when it was a recurring problem (mainly the first time it happend and scared the sh*t outta me) I figured maybe there was a problem with the OD because it would only happen around 55-65 mph so I tried turning the OD off and it continued to happen at exactly the same speed (range).

 

LTC then maybe. If the converter was locking and unlocking sporadically, it might cause this. When you get the truck back, ask them, and be sure to let us know.

 

EPC solenoid was replaced to remedy the hard/shudder shift. Not sure if this will solve the "bang" that I was getting but if that comes back I will sure as hell bring it in asap.

 

The way you describe it I have the same problem, Did it help or you still getting the thump?

 

I sent you a PM, but yes it definitly solved the problem.

 

Something like this occurred on my 99 Ranger. The OD drive solenoid had failed and I had to run in Non-OD mode. The transmission would sometimes go into safe mode and hard shift which gave the hard impact sensation that was described. This would occur in OD or Non-OD mode but mostly in OD mode. I had the transmission rebuilt and was told 2nd gear was basically gone and the OD solenoid was not working.
