is there any way to convert a 94 dodge 3 speed auto trans with a single wire tcc lockup to a 96 two wire lockup. I have a 94 trans but was told it is different > is there any way to convert a 94 dodge 3 speed auto trans with a single > wire tcc lockup to a 96 two wire lockup. I have a 94 trans but was told > it is different The single-wire system switches voltage (could be +5V, could be +12V - check to be sure) to the solenoid to control lockup. The solenoid is self-grounding. On a two-wire system, the supply voltage (probably +5V) is always present, and the PCM switches the ground. If you want to use a '94 trans in your '96 truck, you'd need to use a relay. Connect the relay's coil terminals to the TCC connector of the wiring harness. Provide an adequate power source (need to check whether the '94 solenoid wants +12V or +5V) to the common terminal of the relay, and run the switched output of the relay (terminal #87 on an automotive-style relay) to the solenoid. When the PCM switches the TCC ground, the relay's coil will be energized, and will switch voltage to the TCC solenoid. . . ======= ======= > > is there any way to convert a 94 dodge 3 speed auto trans with a single > > wire tcc lockup to a 96 two wire lockup.

Tom, How would i check the 94 trans for correct voltage and can i use any type automotive relay. Thank you, Harry > How would i check the 94 trans for correct voltage and can i use any > type automotive relay. Get ahold of a '94 wiring diagram, and see if it feeds +5V or +12V to the solenoid. As for the relay, yes - your typical 30A 12V automotive relay from Radio Shack will be fine. >> How would i check the 94 trans for correct voltage and can i use any >> type automotive relay. > > Get ahold of a '94 wiring diagram, and see if it feeds +5V or +12V to the > solenoid.

If the "production" transmissions are the same as the "performance" transmissions, and I think they are, then both the overdrive and lockup are 12V.

Yep, they would be. +12V sure makes life easier for the O.P. > Speaking of knowig his sh.t about transmissions, how about posting the TSB > info you promised last week?

That link is T H E B E S T technical info and printable link that the OP of T H I S T H R E A D has gotten yet. and......damn sure better than what you've offered up so far. so....... go suck a monkeys a.s. or.......give better advice. on second thought.......... forget the better advice....... just suck a monkeys a.s. ~:~ marsh ~:~ > That link is T H E B E S T technical info and printable link that > the OP of T H I S T H R E A D has gotten yet. How? The OP has a '96 truck, which was originally equipped with a 4spd transmission, that he wants to put a '94 3spd transmission in. The link you provided is all about putting a 4spd trans into a vehicle that originally came with a 3spd, non-lockup transmission. Two completely different applications. In your link, it's all about providing electronic switching using mechanical inputs (engine vacuum and oil pressure), to a transmission that's expecting those signals. The OP simply wanted to know how to convert one type of electronic switching to another (2-wire vs. 1-wire). He doesn't need to worry about the overdrive solenoid, as the transmission he wants to use has no overdrive. He will have an unhappy PCM, since he originally had a 4xRE transmission, and the new transmission will not have a governor pressure solenoid or sensor that the PCM will be looking for, but that won't affect the operation of the transmission any. Now... any other sage advice you'd like to offer? > How? The OP has a '96 truck, which was originally equipped with a 4spd > transmission, that he wants to put a '94 3spd transmission in.

Well, there is that, but the OP I'm speaking of had a 2002 Dakota with a 45RFE and wanted info on the upgraded towing flash (TSB MM??) and the shift kits MM spoke of. Too bad NONE of it has shown, because MM isn't as smart as he thinks he is. SignatureMax "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

If none of you goobers can surmise that the simplest solution to the OPs concern is to use a simple vac switch wired to ground the circuit....... then I'm at a loss. I will even concede. I will humbly admit defeat. I will support the original suggested repair...........use a relay...... spend half the day mounting it, wiring it into an ignition feed, running wires down to the tranny, and doing a couple of follow up posts to insure it's being done correctly. All you guys are right. I'm wrong. I provided tooooo easy a solution. or perhaps....... it was that the easy solution was too difficult to locate in the link I provided? yeah.... maybe that's it. maybe..... you guys are not capable of "cross-application" of repair techniques. maybe..... you goobers can't recognize, extract, and utilize a VERY COMMLY USED technique for enabling lock-up on "mutated" trannies, when it's given to you in a link that does'nt directly tell you that it can be used on other models. maybe..... you goobers need something simpler stated in terms that slap yer arses in the face like a brick.... maybe i jest should have said......."disregard the relay, jest tie a vac switch into the ground circuit and be done with it, because it's the EASIEST way to do it." maybe.......i shoud've pissed off the dude that posted the relay suggestion by telling him THAT HE'S OVER FK'N COMPLICAT'N THE WHOLE DAMN PROCESS!" but.....you guys know me......i try to be considerate, polite, professional, and above all.....totally, totally, totally considerate of other posters suggestions and repair techniques. :) but then...... what wudd've been the fun of doing that, we'd've missed out on all this great bonding we got going on. oh yeah...... and about those TWO links that i emailed out.......... keep em confidential....... k? ~:~ MarshMonster ~adds more sage to his stew........mmmm........needs more mushrooms~ >> Now... any other sage advice you'd like to offer? > No Tom, > I'm guess'n not.

Yes, there are... which matters 0%, as the OP was putting in a 3spd... you know... no OD? > please advise me as to what the original tranny was in order for me to > utilize my MOD, AllData, ATRA, Trni, ATSG, GEARS Gee... for someone who does this all day, every day, for 20 years... you sure do like to read a bunch. > experience to better relate to you the logic functions of a Mopop PCM > and how they pertain to detected ratio problems and their actions taken > on rpm drop ....... I couldn't care less about the PCM - since no matter what it detects, or what it tries to do, it's impossible for it to influence the operation of a 3-speed, hydraulically-shifted, mechanically-governed transmission. So - once again... how would it put the '94 3spd transmission in question into "limp mode"? Now... dance around it some more. > > if you will first explain WHAT TRANNY the OP originally had in the > > truck!!!!!!!!
