I was driving and the trany was operating noormal. I stopped at a light and when I excellerated it wouldn't shift into 3rd gear. i checked the fluid level and it was OK. I can drive it and it will shift from first to second but once it trys to shift to 3rd it slipps out of gear, it will shift into rev just fine. Do you know what this could be.

The shift solenoids may not be getting the correct signals from the transmission control module . Read the codes to see if it's the solenoids or the module.
check fluid levels and condition of fluid, look for contaminants in it, change fluid and filter if anything is seen in the fluid..also check detent cable adjustment..may be hanging up at throttle linkage..or cruise control
If you haven't replaced the transmission fluid recently then now is the time. If the fluid is burnt, the transmission tends to fail specially on hot temp. Please do check the transmission fluid first as a first course of action.
auto tranys look somewhat like a jet engine with blades that a pushed by trany fluid. In 3rd or fourth gear these BANDS are damaged. looks like a trany overhaul.
P0733 Trany Ratio in gear 3. This is a trany fault code and the first thing you should check is your tps sensor using your DVOM meter. Measuring the voltages between idle and WOT (wide open throttle), there should be no interruption in the reading (or glitches). Otherwise, it can play havoc to your shifting cycles which can cause this code P0733. If there are glitches, replace the tps sensor right away and reset the code. If trany is suspected, most common fix for this points to a defective valve body. To verify, it can be done by using a scanner which has the capacity to command the trany solenoids so it can be tested at various trany operating pressures.
P0717 is a improper signal from your pules generator A. Which is a the turbine speed sensor on the transmission, You have two of them, the A reads the speed of the input shaft of the transmission and the B sensor reads the output shaft of the transmission. I know with the P0717 it will put the transmission in the limp mode and will not shift past 3rd gear and if your running the transmission hard on third you may have triggered the P0733 which is the 3rd gear slipping. Check the transmission fluid and make sure you have not burnt the fluid, if the transmission fluid is burnt you may want to have a transmission repair shop replace the turbine speed sensor (Pules Generator A) and the fluid and filter. Cross the fingers and hope the transmission was not ran to hard in third causing damage to the third gear clutch packs. Good luck and keep me posted, be glad to help.
First thing is to check the fluid level in the transmission, most vehicles have to be running at engine operating temp either in P or N, check your owners manual. Assuming your fluid is where it should be, that vehicle you have sorry to tell you are notorious for transmission failures, by what you described looks like your going to have to replace the trany or rebuild it, either way its not a cheap fix. My advise if the van is in really good condition put a used trany in it and trade it in for something else. You can look anywhere online about customer/ owner feed backs on 88-98 windstar vans and how bad the transmissions are on those Ford didn't get smart till 99 or 00 when they redisgned the drive train. If you keep driving it the way it is the trany will completely fail leaving you on the side of the road somewhere.
