The contact was driving 55 mph when the transmission failed. 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. 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. Is that the only or most likly scenario? Thinking it is a bad pump but could be the ecu thing as well since the previous tranny went out the same way. Sometimes after its down shifted, it falls out of gear and does it again. Also, although it is listed as a K2500, this is a 1 Ton Suburban.
If you have the V-8 it'll be on the passenger side, under the motor. I have just parked it untill I can figure out what Im looking at in repairs. This was made of cast zinc in some years, and erosion would eventually make a poor connection, with power loss, and all sorts of related problems. The truck drives around fine, except when I'm going up a steep hill. I have a 96 2-4wd suburban that was running perfect and all of a sudden quite shifting gear while I was driving. Then slowed down for my driveway, I pulled in stopped at the end.
Have been driving about 1. I down shifted and it felt like nuteral again. I eased up on the gas and it went into overdrive strong. What are the possible vacuum leaks? I also have transmission problems. The failure and current mileage was 179,000.
The contact stated that the transmission would slip intermittently prior to the failure. Driving it for long periods afterwards sends the grinded up parts all over and cause more problems. First mechanic I asked said without inpection that the transmission would need to be rebuilt or replaced. 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. About 2 years ago the reverse went out and I parked the car for about 8 months.
You may have to shim this starter. Consumer stated that the dealer did not do anything but take the battery cable off to reset the computer and the brakes were never looked at. Firm checked fluid, it was full and didn't smell burnt. The 1995, 1996 and 1997 Astros' transmission woes are mostly restricted to valve body malfunctions. The main power bussing in the underhood electrical center, and the fuse connections there are suspect.
Most shops just replace the parts that are designed to wear out and send it along the way. Then I shut it down. Please note, I have a 4L80-E Transmission. Shut the truck off for about 3minutes, then started it up, put it in reverse and nothing happened, the truck didn't move. I usually hear it when I hit about 35 miles per hour and higher, and it stops when I go below 35. Discovered while replacing the rear axle assembly, the U bolts that connect the rear axle housing to the leaf springs had almost rusted thru. It is hard to say if it can be rebuilt without looking at it first.
If these bolts failed, the rear axle would dislodge from the vehicle with disastrous results. Sometimes I don't hear it at all. Put it in neutral and started it and put it in reverse immediately And it went in reverse then shifted it in drive. It struggles to down shift, the engine revs, then it goes into gear. Transmission not slipping but engine bucking I down shifted to 2 gear then it felt like it went into neutral. 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.
Should be two vertical bolts that hold it in. The contact owns a 1996 Chevrolet Suburban. Wiggle underneath, behind the front tire after blocking the wheels, just because. Put the truck in drive and you felt it trying to move. I pulled over and shut gown the truck. But when it was shifting from 3 to overdrive it felt like neutral.
The tach quit too both at the same time. Drove for about 20 minutes local and highway. I believe its a electrical problem. I hear a whistling sound coming from the front passenger side. And that's it, that's my story! Then I started it and immediately shifted to drive, it went through the gears firmly, then it started loosing power, the truck slowed down. Never makes it into overdrive.
In addition to the switch, any part of the power distribution system could be at fault.

At first when Accelerated It went through the gears. The vehicle was not repaired. 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. 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?
