I just did a head gasket on my '96 80 series and I am a bit stumped. I went through just about everything on the top end. New heater hoses (including PHH), milled the head, new seals all around, new injector o-rings, ARP stud kit, etc., etc.
Everything went together nicely. Engine is back up and running smooth.
Took it out for a test drive and now she won't shift right. First gear will wind up to 4,700 RPM before shifting to second. I have the same pattern for second and third gear. It doesn't matter if I shift through the gears manually or not the pattern is the same. I have adjusted the throttle valve cable. I can get the shifts to soften a bit but the shift points stay at the same rpm.
I have checked the trans fluid levels hot and cold so I know it's not a fluid level issue. I have done an exhaustive search here on Mud as well as Google without much luck.
Are there any 80 Series ninjas here on Mud that can lend some advice or additional trouble shooting?
