Hi All,

I am slowly working through the general maintenance for a 2001 Ford Ranger XLT 4x4 I picked up with 63k original miles. It has the V6 4.0 SOHC engine and the 5R55E transmission. I am already planning to change the transmission fluid/gasket/filter, but have the following problems.

Once or so on my 30 mile commute to work (street and highway) the transmission struggles to shift from 3 to 4. If I apply throttle, it refuses to shift and the car stutters a bit/rpms will not increase. To get it to shift, I need to let off the throttle and then reapply it. It then shifts fine. I also read somewhere that I should put my car in man1, accelerate to 20 mph, and see how well it engine brakes. It appears to not engine break at all. Is this indicative of a bad valve body seal (I csn inspect and replace) or are there other parts I should consider replacing?

Best,
Matt G

Your transmission is totally electronic. Being such, it's difficult sometimes to determine if you have a electrical problem or a mechanical problem with the transmission. So the first thing to do is get it scanned and see what kind of codes you have. You may also buy yourself a half decent scanner, and get one that will tell you what the transmission is being told to do, and you can see if it's following the commands it's being given. Newer vehicles are complex.

Have here same Frame + V6~4.0L~SOHC Engin + 5r55e Trans + 1354 TCase + ... in a 2001 SportTracJob2.
Your describing typical slipping in a 5r55e as they get up in age\miles.
Suspect you've got a blown out ValveBodyGasket, but could be any of several things in the Trans.
Last Trans Service? = PanDrop + RetorqVBBolts + NewFilter + NewPanGasket + BandAdjust + New 5~7qts MerconV; need every 33kMiles\4yrs.
I'd first try HandPumping 24oz ATF from DipTube, replace with a bottle LucasTransmissionFix (extra thick ATF).
If that does not help, HandPump another qt of ATF from the DipTube replace with new qt MerconV then drive 50miles+; repeat several times.
If that does not help, then a FullService if it hasn't been done already.
If that does not help, then a rebuilt ValveBody with ShiftKit + NewSolenoids + BondedValveBodyGasket.
If that does not help, then a full Trans Rebuild.

Yep, you need an OBD2 scanner that will read all TroubleCodes including those for the Trans.

Typically, as Dillard has pointed out, the symptoms you describe are due to a blown valve body gasket. The bad news is that if its been that way for any length of time, there is a good chance that the soft parts of the 4th gear packs are toast. So, in my experience, there are only 2 steps - replace the valve body (they come with the gasket glued on in a way that it is impossible to get it off) and if that doesn't solve the problem, rebuild the trans.
