Transmission problems Why is my truck not shifting out of 1St gear with a roaring noise?

There could be a number of possible reasons why your G30 Chevy van is not shifting out of 1st gear. Some potential causes could include:

1. Faulty shift solenoids: The shift solenoids are responsible for controlling the flow of transmission fluid through the valve body, which in turn affects the shifting of gears. If the solenoids are not functioning properly, it can cause the transmission to get stuck in 1st gear.
2. Low transmission fluid pressure: If the fluid pressure in the transmission is too low, it can prevent the gears from shifting properly.
3. Faulty transmission control module: The transmission control module (TCM) is responsible for controlling the shifting of gears in an automatic transmission. If the TCM is faulty or has malfunctioned, it can cause the transmission to get stuck in 1st gear.
4. Internal transmission issues: There could be internal issues within the transmission itself that are preventing it from shifting out of 1st gear. This could include worn gears or clutches, or other mechanical issues.

It is recommended to take your van to a qualified mechanic or transmission specialist to diagnose the issue and perform any necessary repairs.

Yeah, both the same. You have a sun gear/ planetary gear problem. Basically a transmission rebuild.

This will help.

Thanks.

I have the same problem few days ago, and still didn't find any solution. Can any one please help?????9

If there's a loud roaring noise all the time, then your muffler probably has a hole in it, time to get a new full or partial exhaust pipe.

If the noise goes when it changes gear, then you've probably got a gear box or thrust bearing problem.

Check the fluid level and if it low top it up. However I doubt this will fix it. The bad news is that it sounds like your transmission has had it and the only solution is to get it repaired. Take it to a specialist transmission repairer for them to do a diagnosis, but expect bad news.

Have a shop look at it. It may just be a failed wheel bearing. The bearing will leave you stranded if it gets bad enough and cause more damage.

What you need to check is the transmission release bearing because if there is a clearance on the release bearing you will encounter this problem and also check the transmission oil.

as odd as this may sound, try replacing the fuel filter.

if you have hydro fluid in the clutch master cylinder and the system is free of air, then it needs a clutch
