Code 1870 is well documented on multiple web sites. The aluminum valve housing is too small and wears out quickly. The sympton is a very hard shift from 1-2 and 2-3 as if being rear-ended only after the vehicle is hot. Chevy has reengineered to a bigger valve but still wants it's customers to pay half of $2000 for a $350-$950 problem that should be covered by it's warrenty. Sonnex makes a steel replacement and can verify how frequent the problem is. Chevy's aluminum replacement is questionable, let alone the deal they offer.
2000 Chevrolet Astro transmission complaints
Page 2 of 2: complaints 11 to 19 of 19, newest first, as owners wrote them.
The consumer stated that while driving the vehicles automatic transmission did not shift properly in second gear. The dealer inspected it several times when the vehicle was under warranty but could not duplicate or correct the problem.
When taking off consumer would notice vehicle jerking. While vehicle wa son an incline vehicle would roll backwards. Vehicle was serviced, transfer case needed to be replaced.
When accelerating the van jerks until you resume one speed, and when turning corners it jerks, and when sitting on an incline ready to pull out when you let off the brake it rolls back.............the van only has 23,000 miles on it......the mechanic that looked at this said it is the viscus clutch in the transfer case, and that he has repaired many astro vans with this problem. I bought this from an individual just three months ago, and I am told that this will be anywhere from $1,550.00 to $2,000.00 to fix this. I am requesting an investigation into this model of van (astro), and seeing if this will be a recall and fixed at there expense.I feel a van with only 23,ooo miles on it should not have this type of problem.
Design of sliding door is not well done because door will not automatically lock into place, like in other van doors. Contacted dealer. *akconsumer states; if parked on a hill front end down, door can close by itself without warning. Also, vehicle experiences loss of braking power, traction, on wet/bumpy roads.
Tires wer wearing out on inside , and ABS braking system malfunctioned.. When applying brakes pedal was hard, and vehicle went into another vehicle without prior warning. Also transfer case needed to be replaced.
I am requesting that the vehicle is bought back. No safety defec tmentioned.
Driveline vibration occurs after driving for 15min. Or more. It appears to be related to the awd system.
Vehicle rolls backward on an incline while in drive. Dealer has adjusted transfer case, but problem still exists. *ak
