Drove for about 20 minutes local and highway. I hear a whistling sound coming from the front passenger side. At first when Accelerated It went through the gears. The all-wheel drive versions of the 2000 to 2003 Astro have only a faulty transfer case shift motor to worry about. I have a K2500 5. Usually when reverse goes out the reaction shell has failed.
I usually hear it when I hit about 35 miles per hour and higher, and it stops when I go below 35. If you take pictures with your phone as you go it can make it easier when you don't remember what goes where. And that's it, that's my story! When I started it up I pressed the gas pedal and held it about midway, but the engine reved up And down between 1500rpm and 3000rpms. Never makes it into overdrive. Check theese and give me feed back to further assist you. Started it up and put it in drive and went through all 4 gears strongly no slipping drove for about 2 miles, 45 -60 mph. What are the possible vacuum leaks? If you have the V-8 it'll be on the passenger side, under the motor.
You may have to shim this starter. Then I shut it down. We've kept all defective parts and Chevrolet doesn't want to look at them. The belts are all tight, I have no warning lights coming on. The vehicle was not repaired. The tach quit too both at the same time. One their is not enough tranny fluid in it or the kick down cable is not hooked up properly.
The most common problem with later-model Chevy Astro transmissions is failure of the valve body, which is the central component of the automatic transmission. What year is the truck, anyway? Put the truck in drive and you felt it trying to move. Also, although it is listed as a K2500, this is a 1 Ton Suburban. I eased up on the gas and it went into overdrive strong. Jan 07, 2012 If nothing else, follow the 'positive' battery cable, that's where it goes. Is that the only or most likly scenario? The contact was driving 55 mph when the transmission failed.
The contact owns a 1996 Chevrolet Suburban. Discovered while replacing the rear axle assembly, the U bolts that connect the rear axle housing to the leaf springs had almost rusted thru. Shut the truck off for about 3minutes, then started it up, put it in reverse and nothing happened, the truck didn't move. If I stop and wait for awhile, It will take off like nothing is wrong and within a mile down the road It starts squeeling and seems like it dont want to go. I also have transmission problems.
Some models also had a main power stud at this electrical center made where a larger battery power cable would attach. This problem is not easily recognizable as the configuration of lower plate that the U bolts go thru conceals the rusted portions of the U bolt. First mechanic I asked said without inpection that the transmission would need to be rebuilt or replaced. Wiggle underneath, behind the front tire after blocking the wheels, just because. If you know where to locate it any help would be great! It went about 200 yards and the truck started bucking. The dealer led us to believe that the transmission and heavy engine were covered to 100,000.
Also, the configuration of the above-mentioned plate captures road salt, corroding the U bolts. It struggles to down shift, the engine revs, then it goes into gear. Put it in neutral and started it and put it in reverse immediately And it went in reverse then shifted it in drive. Most shops just replace the parts that are designed to wear out and send it along the way. Sometimes after its down shifted, it falls out of gear and does it again. But when it was shifting from 3 to overdrive it felt like neutral. Please note, I have a 4L80-E Transmission.
In addition to the switch, any part of the power distribution system could be at fault. Then I started it and immediately shifted to drive, it went through the gears firmly, then it started loosing power, the truck slowed down. It is hard to say if it can be rebuilt without looking at it first. The truck drives around fine, except when I'm going up a steep hill. The failure and current mileage was 179,000. The contact stated that the transmission would slip intermittently prior to the failure. Impressed the gas pedal harder and I Hurd the piston rings clattering like the filming was off.
I have just parked it untill I can figure out what Im looking at in repairs. Driving it for long periods afterwards sends the grinded up parts all over and cause more problems. . Transmission not slipping but engine bucking I down shifted to 2 gear then it felt like it went into neutral. I down shifted and it felt like nuteral again. I have a 96 2-4wd suburban that was running perfect and all of a sudden quite shifting gear while I was driving.
