Hello and welcome to just answer and allowing me to assist you. What have you tried so far? Is this an automatic or standard trans mission?
sounds like slippage , have you checked the fluid level while running? How long since the transmission fluid was replaced?
ouch never replaced? ok lets check the fluid condition, Ill give you a chart to see where your fluid falls in and if it smells burnt as well. If it falls in the darker ones then drop the transmission pan to see if there are any particles there .If any of these are present then the transmission probably needs O/H or replaced.The other thing you can do to further diagnose this is have a shop do a pressure test on the trans mission. But if it fails the first two and hasen't had the fluid replaced most likely it's pooched.You can as a last resort replace the fluid but thats a shot in the dark. Hope this gives you some direction where to go to solve your problem and if you require further assistance I'll be happy to do so.
that don't sound too good but if you do those checks as I described I'm positive you will find the problem and solution. I will be interested in hearing what the results you find on these checks.
P0730 - OBD-II Trouble Code
OBD II Fault Code
Fault Code Definition
What does this mean?
The purpose of the automatic transmission is to match the engine's optimum power and torque characteristics to the driver's desired rate of acceleration and speed by auto-selecting different gear ratios or 'speeds' to power the wheels.
Code P0730 means that the Power-train Computer or PCM is seeing greater than a specified RPM difference between the rotational speed of the Input RPM Sensor and the Transmission Output RPM Sensor. This can occur during shifting or when driving at steady speeds in the same gear. It often implies that the transmission is slipping.

P0730 Diagnostic Theory for Shops and TechniciansWhen diagnosing a P0730 code, it is important to record the freeze frame information and then to duplicate the code setting conditions with a test drive. Pay close attention to the engine load, throttle position, RPM, and road speed and compare the Output RPM Speed Sensor signal to the Input RPM Speed Sensor signal. If the input RPM signal varies a lot when you're traveling at a steady road speed and throttle position, then you may have verified the P0730 code setting condition. In other words that code is just confirming my previous diagnoses of slippage and may need to be either rebuilt or replaced you have that option of a manufactured one or used one, but if you choose a used one try for the lowest mileage one you can find and do a fluid flush on it right away. Have a trans shop confirm my suspicions then make your choice to fix your vehicle or find another. Keep in min it's age and mileage to make a good and wise decision. Hope this helps you make up your mind and in the future regular maintenance and fluid changes can prolong the life of you vehicle. Good luck.
if that fluid hasn't bin changed that long and no movement I suspect the transmission ,Two quick checks you can do is check the fluid as I mentioned and to drop the transmission pan to check for particles. Rarely the Ecu unit cause this .
Then you may have a bad neutral safety switch and count your blessings have that checked out it will be at the end of the shift cable right where it goes into the transmission, it's the little black thing with wires coming out of it.so did they say the transmission had good pressure?
Let me know and if you need any further assistance.
