New Life for a truck passed its prime

[farmtruc]

until i can check to see what trans we tuned for, i wouldn't drive it.

[92 6.0]

do you think that you possibly got the banks backwards on the 02s? When I done my swap I done my own harness but dummy me screwed up and swap the banks on the 02s and it done basically what your saying yours is doing. Does it seem to run fine when you first get it started? Mine would run good till it went into closed loop.

Nah it runs like crap anytime. Im bout 90% sure the exhaust will fix it.

UPDATE! Had the exhaust work done today AND got the correct tune from Nelson. It runs a hundredfold better now! So much better that I actually drove it to work tonight.

Interesting note: it would not start today before or after the exhaust work. Culprit: we had run it so much during the time it had no exhaust and was running rich that it fouled the plugs! I mean these things were some of the worst looking plugs I've seen!

Anyway, I am super excited about it running and driving again but there are still a few kinks to work out. The "kink" that worries me the most is that it feels like it has no first gear. It is really doggy from a launch. But once I get goin 30-40 and give it some gas it really goes. I didn't have any time to really diagnose this becase I had just enough time to get back from the exhaust shop and get ready for work. Also, I'm not sure if this is related or not but I have a few codes that are all transmission related:
tcc solenoid control circuit.....
And
somethin else about tcc....
and
transmission pressure switch manifold fault

I checked the fluid level on the trans and is good. Also, it does not achieve converter lockup (obviously related to the above codes).

The next kink is that it always takes two tries to start it. Turn the key once and it fires then dies quickly. Turn the key again and it starts. I'm worried it's not holding fuel pressure....

And lastly, the trans is leaking from inside the main trans connector....how does that happen and how the hell do I fix it?

It's great that you got to drive it to work though!

[flattopwill]

Ya man thanks. It is great to be driving it again.

The trans needs some help! I think it only has 2nd and 3rd forward gears. No 1st, 4th, or lockup. I was thinking that a shift solenoid could be stuck. If shift solenoid A was stuck then I would have 2nd and 3rd but no 1st or 4th. But then I looked at the range reference again and it says shift solenoid A has to be on to have reverse, which I do.

I took it to a transmission shop to have them look at it. They were scared to touch it since its a conversion/swap and dont really know what it is. Something funny there scanner showed was that the TPS was giving an angle (&#37 but no volt reading. Idling or revving the volt reading stayed at (0.00). The gear selector reading showed 4th at all times which is I guess from the tune? The codes it gave were TCC solenoid PWM and Trans Pressure Switch Manifold fault although the guy said the pressure switch showed to be working.

If anyone has any tips on this please help. I am going to drop the pan tomorrow and replace all the solenoids, switches, etc. Hopefully that fixes it.

just please dont set it on fire

glad your up an running, im itching to crank mine over even if the security bs stops it from running LOL. im ready to throw my old spares on an burn all the rubber off of them lol

[flattopwill]

Ya, mine wont even spin a tire with no first gear.......

[flattopwill]

I told my friend to recheck all his wiring today. He said he realized he misplaced the brake switch wire. That explains why I don't have tcc lockup but does it necessarily explain the tcc code it's giving?

We plugged in a Tech 2 scanner today and logged my truck driving down the road. It showed the computer giving the right commands but the trans just isn't receiving them correctly for some reason. I still wonder if it could be a shift solenoid. I was sure it was shift solenoid A but then after I looked at the range reference again I noticed that to have reverse shift solenoid A has to be functioning. I have reverse no problem so I don't know what's the reason for not having 1st or 4th. If I have a tcc pwm code will it disable 4th gear also?
Please help?

I hooked a fuel pressure gauge to my rail today in an attempt to diagnose my starting problem. The fuel pressure does not bleed off quickly and the truck will start and die all while the pressure is still high. If the truck is cold it does not have any problem. If I give it a little throttle when I start it it does not have a problem.

Red? C3? Have a I run out of help me credits?

man i sure wish i knew wth your talking about but i dont.
