[bullhauler69]

Let me pick your brains, I have a 2001 cummins diesel 3500. I just rubuilt my suncoast racing transmission due to i blew my overdrive bearing apart. i put my tranny back in and it wants to drive forward in park, reverse,and neutral. changed the speed sensor and pcm. but still nothing , also the alternator is not charging and the a/c, i put the snap on scanner(solus) on to test all relays any the transmission relay does not click but relay is good, the ac relay that activates the clutch does not click but relay is good all relays are checked ok, what the **** is going on help me out here

sounds like you have some issues! we`ll try to help, not sure they are all related but we`ll see...the trans sounds like something to do internally, but i`ll mention it now i havn`t been in many transmisions, anyways (: could be something simple is not connected or sheared and shifting to your desired position. as for your alternator it could be as simple as battery connections or cable conditions, or a problem with the pigtail attaching to the alternator, or the unit itself, the a/c could also be electrical related or that the pressure in the system is lost and the compressor wil not cycle without a set pressure requirement. letme know what you think > stump

Everything in transmission is fine checked over 5 times literally, all these problems happened after the fact the transmission was installed. all harnesses are plugged in, batteries are good (load tested), terminals are clean all grounds are good, im pulling my hair out over this truck

[stumpuller454]

hmmm its gotta be an electrical problem, have you ohmed and checked voltages at required terminals? oh do you have a factory service manual for your truck?

[bullhauler69]

yes I have, your not suppose to get anymore than 5 volts going to the sensors, i have 4.55v, so that checked out fine. I also have a service manual (haynes) and it hasn't helped at all.

[stumpuller454]

what did you get for resistance on your grounds?

[bullhauler69]

at all my ground points Im getting no more than 2 ohms

[stumpuller454]

should be less than .5, but see what resistance your meter has internally, if it says 1.5 by itself you wires are probly .5 so good to go.... I wish i could help you more man ima chevy guy but i know i`ve had many problems with grounds on them dodges a few times, just curious have you unbolted your underhood fuse block and taken a look underneath? sometimes problems can hide right under those units....and not to tick you off but are all your connectors in the right connectors?, not sure how many would require unpluggin when doin the tranny but but it was common that dodge liked to use alot of the same style connectors...(: >stump
