SOURCE: transmission does not shift and speedometer does not work

replace the input and output transmission speed sensors, they run about $20 a piece you will need a 1" deepwell socket to easily replace these. It took me about 45min or so without deepwell sockets but would have taken about 20min with them.

This same thing happened to my daughter,s car, and it ended up being fixed with a transmission speed sensor. This sensor not only runs the speedometer, it helps tell the transmission when to shift too.

My speedometer isn't working in my Acura mdx 2005 and it won't shift outta first gear ?!

the speedometer is more then likely due to a fauly speed sensor on the transmission, presuming your check engine light is on, try resetting ecu by removing battery cables for 5 mins, then plugging them back on battery, ensure you have radio code before doing so to avoid locking the radio if it is still the stock radio, if problem is not resolved check engine codes for possible fault shift solenoids, also ensure there is enough transmission fluid, to check turn the car on let run for 10-15 mins to warm up oil, block the wheels and place transmission in neutral and verify correct level of oil, if no codes present and oil at right level, suspect a faulty torque converter in the transmission.

Recently replaced speedometer sensor on my 2005 Chevy Tahoe speedometer still does not work do you know how to fix it

Yes , replace the stepper motor inside the instrument cluster . The speedometer sensor as you call it is actually a VSS - vehicle speed sensor. If the transmission shifts good an engine runs good it's not the VSS bad. You have to know how it works to fix it . The VSS is an input to the PCM/ECM - engine computer , The PCM/ECM calculates engine speed then sends this info to the instrument cluster over the serial data communication bus . GM has had bad stepper motors in that year vehicle . How to repair GM Instrument Cluster Speedometer Gauge Stepper

99 tahoe read code p0300 what does that mean

Po300 is a multiple random misfire there several things that cause this GM had an issue with the coil wire arcing to the transmission dipstick tube the new routing is to go over the plugs and remain on the inside of tube (old way was behind) USE a new wire. #2 dirty fuel (water contamination) As for the p1345 code this could be caused by ignition arcing inside Distributor Cap I would suggest replacing cap and rotor Clear codes This code will set once engine has gone over 1000 rpm's it updates every time to get spark advance correct if sets again distributor has moved this can be reset with a gm specific software scanner under camshaft offset specs 0 degrees to +4 max.

Fuse # 20 or 21 gets power through ignition. This fuse controls PRNDL indicator, speedometer, tach, & will cause transmission to not shift gears correctly. Ours took off in 3rd gear when put in Overdrive & only ran in 3rd gear. If we tried to manually shift thru gears (auto trans), it had 1st, 3rd, reverse. No 2nd or over drive. Replaced ignition. Fixed problem. Root problem was Electric motor that engaged 4 wheel low side was bad. Every time we used 4 Low side it threw power surge through ignition & blew ignition out. Good Luck.

Will shift solenoids cause peedometer to not work and i have no 3 or o/d

NO. But a speedometer that is not working will cause the transmission not to shift correctly and may not allow over drive to work, the first thing is to find out why speedometer is not working.

The most common problem for that is the speed sensor, try replacing the speed sensor and see what happens. this sensor is located on the transfer case near the back if this is a four wheel drive truck, if it is not then it is located at rear of transmission on drivers side. let me know good day

GM OBD2 code 1345 causes

either the crankshaft sensor needs to be changed or camshaft sensor.Both work together and are under that code.If you change the sensors you will need a crankshaft profile correction.This should be done by your dealer with the proper scan tool.
