2005 Ford Taurus Transmission Slips from 2-3. 1st - 2nd is good, 3-4 is good. I had the torque converter replaced a year ago because it busted the shaft.

Any idea - could it be a solenoid? Fluid is fresh and red with no grit. Levels fine, no whine.

If it is more of a delayed shift, I would start with the 2-3 shift solenoid. If it is actually slipping (can make it slip after shift is complete) then I would say you have a worn clutch pack. Since the fluid is clean, my first guess would be the shift solenoid.

Thanks. That was fast.

I can get it to slip once it is in gear.

I fear it's a dual problem, solenoid and clutch pack.

I've pulled a lot of transmissions and rebuilt lots of engines, front ends, shocks, struts, brakes over the years (I'm 49) but I've never messed with an Automatic Trans. How hard is it? Should I buy the ATSG manual 86400H for the AX4N? I've got plenty of time, since this is a spare car.

Honestly, if you can get it to slip once it is in gear, it sounds like the clutches are spent or there is really low trans fluid pressure which I doubt. As far as this type of rebuild, it isn't that bad to do. Basically, it is a soft parts overhaul, clutches, seals, gaskets. Yes, I would recommend getting a good repair manual. Make sure you have a sliding dumbell to get the front pump off. Also, when you put the clutch packs back together, MAKE SURE the clearance between them is within spec. If you don't and they are too tight, you will end up with what feels like a double shift. If there is too much clearance, it will have a delayed soft shift and will wear the new discs out quickly. Inspect everything when you have it apart for stress cracks. Also, make sure to replace all thrust washers that will come with the kit. Based on what you have done in the past, take your time, get the manual, and it sounds like you will be fine. If you run into trouble, let me know.
