I have a 1999 f250 4x4 triton v10 tho odometer works now and then it shifts hard out of first and drive is like netural

Sounds as if the spider gears are going bad. There are bands or belts in your tranny for each gear. They may be going bad. Have you checked the transmission fluid level? This also could be the most obvious reason. Just
Low fluid level? Noticed any drips in the driveway ?

Check the transmission fluid level. Also check the rear differential if your car has one ( I think the 99's were still rear wheel drive) for fluid. If either of these are low, the fact that things are fine indicates that the low fluid level is causing problems. Also, the trans fluid should be a nice pink color. If it isn't then the transmission is not in good shape and should be looked at again by the rebuilder. If the fluid levels are fine, have the rebuilder check the trans again to see if he missed something.

The issue with the temp gauge is entirely separate except if you mean that the car begins to heat up when the shifting problems are occurring. If the temp gauge goes way up then comes down quickly regardless of how the car is being driven, the thermostat may be sticking and should be replaced. If the car is hard to drive and then starts overheating, the transmission may well be defective and causing the engine to work harder than it should.

Hi, have you checked the fluid level and when was the last transmission filter replacement?

hi, it may be the transmission oil, transmission oil LEVEL or and transmission filter.
first check transmission level by starting the engine (ticking over) go through ALL GEARS and check level. this level will (drop from standing idle). NOT ENOUGH FLUID
if the FILTER is partially blocked then not enough fluid reaching the chambers. NOT ENOUGH FLUID.
the fluid may be full of deposits. transmission fluid needs REPLACING and or FILTER.
also check if leaking transmission fluid.
check if lever out of range (worn, can't get to position before end of gear lever travel).
the brake bands may be WORN, or needs adjusting
the KICK-DOWN seams to work. check link-ergs for wear and movement.
the speedo seams to have a BAD CONNECTION (closed circuit connected then open circuit). loose connector. gerry

Check the transmission fluid level... they'll make noise and complain when they don't have sufficient fluid to operate.

while on level ground, start truck, shift tranni to netural, step on brake, shift from 4 low to low hi either through lever or push button which ever one you have. problem solved.

the first common possibilty would be to check fluid level, if the fluid level is good, I would recommend changing the transaxle fluid and filter. if this does not correct the issue, a professional transmission repair person will need to diagnose for you, good luck!

Check the transmission fluid level and condition. Make sure the level is correct, if it is then it may be time for the transmission for service. The transmission service time is every 30,000 miles, and if it has not been serviced the Transmission line pressure solenoid could be gummed up with dirt. Have the transmission fluid flush and the transmission oil filter replaced and hope that helps. Hard shifting is a sign of fluid restriction in the valve body in the transmission and will lead to a costly transmission failure. Good luck and keep me posted, the other thing to that would give you a hard shift is a bad throttle position sensor. But that should have given a check engine or service engine light on. 

if it is a automatic gearbox check the level off the gearbox oil if it is tho low it starts tho shift pritty hard

Check the transmission, my friend had that on his Ford and the transmission died about a month later.
