No way to know that until the transmission is diagnosed and the systems control model scanned.

Sounds like your trans is stuck in limp in mode. Could be something simple as a sensor, or something major as the trans or the computer. Will need to be computer diagnosed.

SOURCE: Auto Transmission in 94 Chevy K1500 will not shift into 2nd gear

Hi, yes I just had the same problem and the clutch packs inside the transmission are slipping. I had to replace all the clutch packs as well as the bands. The parts for this job really aren't that expensive. you could get everything you need for less than 300 bucks. however labor is where they kill you. It's about a 10 hour job or maybe 12 depending on application. average shop rate 80 an hour you looking at 900 dollars labor plus parts. if your mechanically inclined and have tools you could take your time and do it yourself. you can buy a step by step DVD for your specific application. other wise I would call around to transmission shops. their is a slight chance it may also be your solenoid pack. the best way to confirm is to have a transmission line pressure test done. I hope this helps!

SOURCE: my 2003 h2 hummer will initally not shift from

Check the linkage that goes from the shift lever down to the transmission. It sounds like somewhere along the line, it has become disconnected or has broken.
if that parts are clean then It sounds like you have a shift control solenoid that has high resistance causing the hard shift you describe. Scan the PCM for trouble codes if none are present you could have a internal transmission problem.

At what RPM 1st gear should shift on a H2 Hummer 2003


well is that hummer that a 2 ton or 4 ton vehicle ?

would take a lot of revs for first gear to make it roll from a standing start
think it will be fitted with an 6 speed automatic transmission

guessing only from my heavy vehicle driving experiences
first should change below 3000 rpm

if transmission was slipping in first gear you would know

suggestion
ring up the local hummer service division for the correct answer

My transmission wont shift out of 2nd unless you stomp it to 4000 rpm and let off


Sounds like your shift solenoid is sticking. Check your fluid level first. The next logical step is a filter change. You could be getting low pressure from a clogged filter. The next thing to try is a power flush on the system. If none of that works. Then it's time to R&R the tranny because is one solenoid is sticking, they all will start soon. Just so you know, I had the same problem in my Durango and a new filter cleared it right up. Mine was a 98 and I sold it with 179k on the original transmission. That tranny is generally bulletproof, but you have to keep up with the filter changes and fluid changes. And it's a good practice to change the gear oil in the differentials when you change the tranny filter. That way you have a well lubed drivetrain and you can eliminate the issues related to neglected drive components. Then the next time you do it, you will know how long it's been for each. Good luck.

This trans has a safety built in to default to second gear if the computer sees any kind of problem. Have it scanned. It can be an input or out put speed sensor, or even a temp sensor on the engine. If there are codes that say ratio error, take it back to who rebuilt it and hope they will take care of you. I use to give a major discount if they were not too far out of warranty.
