  1. So this weekend I got some solid time to investigate. I double checked all the connections, checked the gap on the tone ring, and went for a test drive. In drive, it goes through all of the gears and into overdrive, shifts down to 2nd when I manually pull it down, but it will not go into first gear when i pull it into first at a stop. Now time to look into that. Thanks for your help Moses!
  2. Last night I swapped out the PSOM and MLPS from a good running vehicle and i got the same issue. No codes shifting poorly, not going past third. Then I gapped the VSS from .045" to .02" from the Tone ring and began getting a different reaction from the transmission. It was shifting through 3rd and would jump into OD then back out then back in. I believe the VSS is the culprit (even though it is brand new) so tonight i will swap it out to see if it is truly the issue. Thanks for your help y'all.
  3. So tonight I found out that my 1992 did not come with 4wabs. The VSS is wired straight to the PSOM. I attempted to wire the VSS directly to the computer but it would kill the engine once the tires were moving. So I put it back together as factory and now I am thinking I will try my buddies PSOM. Any other ideas?
  4. Update: I had the EGR delete plug in incorrect, swapped it around and the 624 & 629 code went awAy. But the shifting problem is still there. I replaced the solenoid pack and went through the valve bodies with my Trans builder and everything checked out. I cleared the codes and I am not receiving any codes but the Trans still is not shifting correctly. The Trans builder recommended replacing the psom or bypassing it. Is it possible to bypass it? I am at my wits end with this thing. Any help is much appreciated.
  5. Moses thanks for the reply. Last night I put in a new TPS and have correct parameters now so that eliminated codes 334 and 336. I cleared the codes and warmed up the engine on jack stands then gave the Trans another go. Engine started up perfectly, idled smooth then put her in gear and it shifted hard from 1st to 2nd, then the OD light began flashing. I pulled the codes and 624 and 629 came up. Tonight I will check the connectors at the transmission for any irregularities. Thanks again Moses
  6. I hope this is the forum that will help me put my Trans problem to rest. Here it goes: 1992 F150 5.8l 4x4 and an E4od. I just rebuilt the engine, added Mass Air Flow and deleted the EGR. At the same time I had the E4od rebuilt and hD brand new for solinoids installed. So I installed the drivetrain and now I am having shifting issues. I am able to put it in drive and it will sometimes shift to 2nd but then at 55 it will not shift to 3rd then is hard to downshit. I have put it up on stands and it does it time and time again. I have installed a new VSS in the rear ended and the speedo reads perfectly. I pulled the codes and I am getting 334 and 336 but nothing for the Trans. I have disconnect the negative battery post for the night and plan on getting back into it tomorrow after work. Any help on this is much appreciated. Where should I start to weed possibilities out before I pull the pan?
