    Since you already have a high pressure pump, that's an option. You would have to add in a knock sensor to the drivers side as the 4.3l...

    That little white clip goes into the spider injection plug to lock it in place. As to your plugs, that sounds like normal wear for...

    Have you physically removed the rear speed sensor and looked inside and seen a square 40 tooth reluctor wheel? My 95 4l80e also has that...

    Just because they're factory, it doesn't mean they were factory to that truck. For all you know, somebody could have swapped the engine,...

    They made tcm's that didn't need the output speed sensor in the trans for 4x4's, it was just the one's used in the 91-93 trucks that...

  6. THEFERMANATOR replied to the thread 4L80E driving me crazy.

    Doesn't work that way. The 91-93 trans has both trans cooler lines hooked up at the bell housing. Sounds to me like somebody cobbled...

    Acdelco double platinum is the primary go to plug I run in them. They used to have an iridium, but I haven't seen them in awhile.

  8. THEFERMANATOR replied to the thread 4L80E won't shift until it is warmed up.

    You're going to have to check the voltage going to the trans when it does it. The systems you arehaving problems with are all powered...

  9. THEFERMANATOR replied to the thread 4L80E won't shift until it is warmed up.

    Sounds to me like you have a power issue. Turning the 2-3 solenoid on is pulling the voltage down. The cluster and trans I believe both...

  10. THEFERMANATOR replied to the thread Cooling Problems on my 2007 2500 LBZ.

    240-245 is where things start getting hot. It's not like the olden days where people freak out at 205 as the stats are just really...

  11. THEFERMANATOR replied to the thread 4L80E driving me crazy.

    I would have to see pics, but GM never built a 4l80e 4x4 after the 93 model year with a reluctor wheel installed in the tail end. They...

  12. THEFERMANATOR replied to the thread '97 Sierra Z71 5.7L Vortec OBDII Codes.

    The vortec engines origanally came with plastic intake gaskets. If they haven't been done by now, I'm shocked it's made it this long....

  13. THEFERMANATOR replied to the thread Cooling Problems on my 2007 2500 LBZ.

    Factory stats don't go full open until 230-235 degrees. These engines can take alot more heat than most want to run. I ran for about 6...

  14. THEFERMANATOR replied to the thread 94 TBI 350 with a rod knock Refresh time.

    The difference is in the pistons. The heads have different valves and exhaust seats in the 8600 gvwr +. 8500 and down is supposed to be2...

  15. THEFERMANATOR replied to the thread '97 Sierra Z71 5.7L Vortec OBDII Codes.

    I'm going to guess you have multiple issues here. I know O2 sensors in these trucks can cause all kinds of bank rich or lean codes...
