information please

I have just purchased a 96 s-10 with 4 cyl. auto. It has several codes being displayed. p.o. 300 p.o. 140 p.o. 753 p.o. 171 p.o. 1406. I have done tune up (replaced wires and plugs) runs alot better . I read that the ses code has to be manually reset. But after reading some of the other post I think I'm wrong . Any information on where to find more tech. info would be appreciated. Thanks in advance. :headshake

Update on codes. Went to auto zone found only have one code left 753 ,has to do with transmission. I'll take down next week. If anyone knows of source for transmission shift I would appreciate info.
Thanks in advance!!!

Follow up on problem . Code 753 is transmisson code for shift circuit . It seems all 700 codes are transmissions, any way took to Blair's tranmission shop and they changed solenoids and serviced runs good now all lights gone . FYI Blairs is located in Dallas off Buckner. Ihope this helps other people don"t let a shop rebuild without first checking it out . If a shop says rebuild right away ask them to try to repair without instead of just rebuild. If they are a good shop they will respond . Not all problems require rebuild. Hope this helps
