    I am having a problem with my tranmission of my 04 chevy suburban it will move when I shft it into reverse and into the low gears but will not move when shifted into drive or 3rd gear. What could be wrong??
  • Interesting ... I just got my 04 suburban back from the transmission shop today.

    Reverse, 1st and 2nd gears worked. 3rd and 4th didn't work. Total mileage : 124K
    At ~30mph it tries to shift into 3rd gear, you can see the RPMs increase, but there is no speed increase.

    The problem was that 3rd/4th gears didn't have any friction material (worn down to the metal) and there is valve that wasn't working correctly (thus no 3rd or 4th gears). Had the transmission rebuilt and it now shifts smoothly.

    Cost ~2K.

    i have a 2005 suburban with 50k miles. light throttle 35-45 mph trans in overdrive feels like your on the rumble strip. more throttle pressure or less or put it into tow mode on gear selector, it stops shuddering.....will be ok for a while, till next episode. seems like maybee a pressure switch or the need for a update computer re-flash...what 'ya think? i always get good info here...thanks in advance for any info/help.

    My 98 burb is doing the same thing now. What did you have to have done? I just had it towed to the transmission shop and am waiting to hear what they say. THanks for your info!
  • all i did was change out the tranny fluid and filter and it runs ok
    but i also think a new torque converter will fix it for good
  • My 2007 Chevy Suburban won't engage drive or 3low. It works fine in reverse. In 2low it runs fine unless I turn or go above 20 mph. Then it sound like something is rubbing on the front wheels. Had a horrendous snow storm today and had the vehicle in 4wd. This didn't start happening until tried to change back to 2 high. What could this be? Has anyone else had this problem?
  • I have a 2000 burban 2500 4 x 4 and it has been doing the hard shift since about 2004. It shifts fine until I go on the freeway and cruise for awhile. I went to a transmission shop back in 2004 and they put the Scanner on there and told me it is a convenience issue but will not hurt the transmission. They said I could fix it for about $400. Here is what I was told in my unprofessional language.

    There is some kind of valve (my words) that engages once you get going a certain speed (like on the highway/freeway) and it sets. Then when you stop going fast (let's say you get off an exit and come to a light) the valve sticks and causes the hard shift. I have found that if I turn the truck off and turn it back on it resets. So like I said previously I have been driving that way for 5 years and it still does that today but it does not stick every time.

    My understanding is that this so-called valve is like a small metal "dowel like" plug that slides back and forth depending on the speed and gets sluggish and does not always slide when it is supposed to. Weird explanation but I did not ask a lot of specific questions. I was just happy that it was supposedly no big deal and only a driver convenience/aggravation issue. This was my experience. I am not a mechanic and really don't know much about my Burban since it has given me great service and I have not had many problems except for now and that is why I am on the forum but not for a transmission problem. I hope that helps.

    This turned out to be real interesting....under used veh. warranty. took it to the dealer. I was really surprised when they replaced the transmission!....said it had a broken "part" and water in the transmission!....I got it home ok. Next cold start, "bucked" like a bucking horse...nearly cut off. Eventually, engine light came on. Onstar said it was Transmission. Took veh. back to dealer. They replaced the manual valve pressure switch....code was p1810.
  • I got an 1870 transmission code - transmission part slipping. Any advice?
  • 2000 Suburban 2500 6.0L

    Can anyone tell me where the oil filter is located. I looked for it did not find. I am going to jack it up so I can get more room to move and look again but if someone knows please reply.

    Also does anyone know what an 1870 transmission code refers to. I know it says "transmission part slipping". Would this mean the torque converter? Fluid level is good and I don't feel anything when driving.
  • While driving and while the suburban (year 2000, 2WD, 1500, LT) was moving at around 20mph, the suburban started to lose power so I had to push down the accelerator much harder for the suburban to continue moving. Finally, the RPM got too high so I let off the gas and let the suburban roll to a stop.

    After stopping the suburban didn't move at all after pushing the gas. I turned it off, and back on. Right after the engine turned on, I heard a one metal bang under the truck. Now, I continue hearing this one bang every time I start the truck.

    When in any gear, (Drive, reverse, 1, 2, or 3), the truck won't move when pushing the gas. However, once every 10-15 starts, the suburban starts moving in either drive or reverse (apparently responding to the push on the gas) but soon after (30 seconds later) stops.

    I checked the transmission fluid and it's overfilled 1-1.5 inches over the 2nd dot. I don't know if that's way too overfilled to cause this problem or not. Maybe, it's not the problem at all.

    I regularly take the truck to the dealership for regular service (oil change, fluid topoff, etc.) The last time fluid was added according to my invoices was in April '09. But the last time I took it to the dealer for service was for an oil change and according to the service center, all the fluids were "OK" and none were check marked in the "filled" section.

    I don't take the truck anywhere else for service, so either the fluid was overfilled in April or December but not noted on the invoice.

    Any thoughts on this problem???

    Something broke in the transmission. Get it towed to either the dealer, or a transmission repair company.

    Am almost at wits end.

    I had to replace the transmission in My 07 Suburban (2WD) at 65m miles. (For what its worth I have never towed anything) I took it to AAMCO, I got the car back and 1 1/2 weeks later it went again. Two weeks ago I got the car back again , it just went again yesterday.

    Am looking for some insight. Is there a problem with the car? Or did the AAMCO I took it to just not do a good job (twice). For what its worth I was 2 hrs away from home when it went this time, so it's at a different AAMCO.

    Thanks,

    Gerry
  • If it only had 65k miles then why did you not take it to the dealer. It has a 5 year 100k mile drivetrain warranty. At least my 08 came with that and I purchased the bumper to bumper 5 year 100k mile for everything else that may break.
  • mlackey,

    Exact same problem with my 2007 Suburban today. Exit highway and stopped at lights. Went to drive and nothing, might have gotten into first gear, but as soon as it went to shift into second, clunk, and nothing. Will not engage in D or 3 low, but was able to make it home in 2L. Did you have any luck getting your problem fixed?

    Cheers
  • My wiper blades lasted longer than my transmission.Had to have transmission overhaul done at 60,000 on 2007 Suburban. In the process of putting the 3rd battery in the car, just replaced it in April 09. Not looking forward to the future with this vehicle, battery demise is random, onstar diagnostics claim everything is okay with vehicle, then you go to start it and the battery is dead. No problem hit the onstar button and get roadsise assistance. Oh wait, onstar doesn't work if the battery is dead. $45,000 POS!!!!
  • exact same problem with mine. I backed out of my driveway, put it in drive. I heard a strange noise, then couldn't move forward. I can start out in 1st, shift to 2nd (makes a strange noise), then shift to 3. D does not work. Took it in to the dealer today. It's covered under warranty. I'm at 85k miles, I'm glad it happened before 100k!
  • i have an 89 subarban that had a leak due to a bad converter. i replaced the converter and now it will not go into reverse. is there anything i might have not hooked up right? a quick reply would be great as i need to make a long road trip with it this saturday. thanks.
