My 2004 Chevy trailblazer wont let me go when I put it in drive it wont let me drive also when input in reverse same issue I have transmission fluid in it just wont move

There are a few potential causes for this issue in a 2002 Chevy Trailblazer, including:

1. Transmission issues: The transmission may be damaged or malfunctioning, causing it to not shift into gear. If this is the case, it will likely require professional repairs or a replacement.
2. Shift solenoid failure: The shift solenoids control the movement of fluid in the transmission, and a failure of one or more of these solenoids can cause shifting problems, including not being able to engage any gears.
3. Electrical issues: The transmission may not be receiving the correct electrical signals from the transmission control module or other components, which can cause shifting problems. This could be due to a problem with the wiring, connections, or other electrical components.
4. Low fluid levels: If the transmission fluid is low, this can cause shifting problems, so it is a good idea to check the fluid levels and add more if necessary.
5. Clutch or pressure plate problems: If the clutch or pressure plate is damaged or worn, this can cause shifting problems, including not being able to engage any gears.

If you have checked the linkages and fuses, and are still experiencing the issue, it is recommended that you have the vehicle inspected by a professional mechanic to diagnose and repair the problem.

Dexron Vl

Walmart has it under its "SUPER TECH" line of products. $4.27 per quart.

11.2 quarts from dry, including torque converter. When just changing the filter, between 5-7 quarts. Dexron 6 is the best, and newest technology from GM.

have a pressure test done on the transmission to check for internal problems. run fault codes to check for TCM and other related faults. Have a band and clutch pack adjustment done . If it all checks out but the problem persists then you may have to consider a removal and overhaul option.

Have you checked transmission fluid recently. If the levels are low and/or if the dipstick smells burnt, there is a good chance your transmission is shot. Check it out & let me know; may have another idea if the fluid level checks out.

ok my problem is my chevy blazer is that my reverse wont work and that even in neutral it still goes forward like its in drive any body got any suggestions

Your transmission/transfer case needs to be flushed and the fluid replaced along with any needed screens or filters that are recommended by GM.
Your owners manual should have info on the manufacturers reccomendations.

your shifter linkage may need adjusting at the mounting point on the transmission. it may be off a little making the car's computer think you're still in reverse.
