97 Windstar

[Wolffe2002]

A couple of problems, one the tranny seems to shift hard from park to drive only when cold all other shifts seem fine. Is there some easy fixable reason for this? Its not slamming hard but its enough to slip the wheels on snow. It has the tranny and steering coolers on it and was looked after, but that doesn't mean too much on these things.
(I don't need to be told that windstars are known for problems, that is no help)
The other problem is the DRL won't come on, all the other lights seems to work as they should but the DRL's don't. The fuse is fine, I am not sure where the module is on this van. Where should I look first? Is there anything else inline that might be the problem?

I have a '96, so that is what my data is based upon.
I do not have a DRL module, but for '96, it is listed as being in the engine compartment, driver' side, front.....looks like it would be in front of the battery. Do not confuse it with the CCRM, if you have one.
I also see a note that states that the DRL module gets very hot during operation.....and to let it cool before trying to handle it.

Shifting. Hopefully you have the correct fluid in your transmission for your year.
Also, you can try checking the transmission fluid level.....with the engine WARM, on level ground, gear select in "P".

There is a transmission fluid temperature sensor inside the transmission. This is used by the PCM to compensate the shifting and torque converter operation to account for the temperature of the fluid. I can see how a problem with this can cause rough shifting.
This item is inside the transmission, on the main control valve body.
Replacement involves tearing into the transmission.
I would think that you are fine as long as the other shifts are OK.
Mine is a little abrupt when cold going into drive. I usually notice it going from Reverse to Drive after backing out of the driveway....but only when it is really cold.

In front of the transmission, in the metal fluid lines that go from the transmission to the coolers is a small metal square'ish block. This is a thermal switch. When the fluid is cold (like 32 degrees F or lower) the switch causes the fluid to bypass the coolers, and go right back into the transmission. This would prevent the fluid from being over cooled. Above the cold temperature setting, the fluid flows out through the coolers and back to the transmission.
I mention this because I have seen discussion concerning overcooling the fluid during real cold weather....and this should not be a concern on the windstar with this thermal bypass.
