Two problems related to automatic transmission torque converter have been reported for the 1999 Chevrolet S10. The most recently reported issues are listed below.

car   Automatic Transmission Torque Converter problem 1
Failure Date: 02/20/2007

I had a "service engine soon" light come on, had it scanned, it was trouble code p1870. Chevrolet customer service could not tell me what the problem was. . . My mechanic told me had to rebuild my 4l60e transmission and/ or torque converter. Instead will replace the torque converter regulator valve with a sonnax tcc regulator valve kit. Seems to be a very common problem with these transmissions from 1999 and back.

car   Automatic Transmission Torque Converter problem 2
Failure Date: 10/01/2002

After a previous day of uneventful use,I noticed on the morning of 10/1/02,that after starting, the truck would only shift into neutral and reverse. When an attempt was made to shift into drive,the vehicle froze. The truck was then towed to a transmission shop,and the problem was diagnosed. The 4l60e transmission had to be rebuilt as well as a torque converter,which was literaly torn apart. The tranmission specialist asked me how many miles were on my truck,and when I told him, (only 56,000) he explained that this problem should not have occured in a vehicle with such relatively low mileage. In fact after examining the defective parts more closely,he concluded that the failure occured as a result of the faulty way in which these parts were machined. The total cost for all of this was around $1,284. 00. Attempts were made to contact gm,but they were unwilling to accept responsability. I understood,as I explained to their service dept. That my 36,000 mile warrenty was up,however since this failure was as a result of a flaw in manufacturing,and not normal wear and tear I was within my rights to ask gm to accept responsability and reimburse my expenses(at least partly). The service department's form letter response was "I"m sorry we can"t help you". My reason for writing all of this is in the hopes that more angry consumers like me will come out of the woodwork and create a voice loud enough that gm will no longer be able to ignore. B. W.
