E4OD 1st gear problem
My wife's 94 F150, 300 six, E4OD suddenly developed shifting problems - wouldn't come out of park. I adjusted MLPS and cable linkage, to no avail. On a hunch, I checked the fuses, and found #13 blown. That lead me to the brake pressure sensor switch on the master cylinder, which had developed an internal leak, destroying the internals of the switch and allowing the connector parts to short out.
Replacing the switch solved that problem, but now we have to take off in 2nd. If we shift to Drive, the truck jumps and snorts and makes banging noises from the transmission. I checked the fluid, which we've always kept topped up and changed on regular intervals, and it is brown, and about 3 inches too high on the stick. I know brown = bad, but too high?
I opened a coolant line and drained off about a teaspoon to test for anti-freeze, but how do I test for this? Shake it up, throw in a match, take it to an anti-freeze repair shop?

You don't have to test for coolant. If there is coolant in the fluid it will look like a strawberry milk shake, or if the fluid is burnt first, a pale chocolate milk shake. If the fluid is just brown but overfull, somebody added too much fluid. Brown can be either burnt, varnished or old.
I would first check the MLP and see that it and the linkage are adjusted properly. If so, its time to find a good transmission shop to do more extensive diagnostics.
