I have a 2000 Chevy S-10 ZR2 with a 4.3 litre 6 cylinder engine. it has 107,000 miles. The service engine light came on a few days ago and I had a code reader attached yesterday. it says the problem is with the shift 1 to 2 circuit. What will correcting this entail and what will the likely cost be? Does it need to be corrected? The truck seems to run fine but I have noticed it having trouble going from drive to overdrive when going down the highway but do not know if that is related.
