trans help plez?

[va3jco]

got a 80 3/4 ton 4x4 with a 3spd auto with a cast iron tranfer case, the trans is done, have a 88 burb 4x4 with a 4 spd auto will it fit the truck, the cast iron tranfer case and the drive shafte out of the 3/4 ton or am i dreaming here, i need lots of help i think

Does the burb have a complete drivetrain?

[va3jco]

yes

Then I'd use all of it if it was me, then the only thing you might have to change would be to find a 3/4T rear driveline out of a similar year as the burb since the 14 bolt has a bigger U-joint. The front should fit like it is. However you are going to have to bring the 700 trans to me so I can redo it to work without an ECM No you can do it your self or have someone that knows 700's help you. You need to add a TCC valve train in the valve body out of a pre 87 and change to an older TCC switch Assy. If I think of anything else i'll get back to you.

no, you can buy a TCC lockup kit through any of the major mail order places, and it will do the job just fine. that trans has ZERO computer controls on it, its all straight 12v, a vac switch, and the brake light switch is used to cancel it. there is nothing else involved, PERIOD. www.73-87.com used to have a writeup on how to wire the TCC using all stock parts, and you dont even have to pull the trans pan.

Well there's an old saying, you got your version, I got the truth. And just what is going to control the operation of it without an ECM? That's why the older ones have a separate shift valve and throttle valve just for that. You don't need some elecronic POS controlling what the trans can do itself. And what do you think you need a vacuum switch for, the only one they ever used was controlled by water temp so it would not lockup until the engine was warm, which in turn would allow the trans to warm a little too. It just tickles me that people think they need all this aftermarket BS to make such a simple thing work. He has everything he needs to make it work and needs to buy nothing PERIOD. Or maybe why not do like some of these no nothing rebuilders and just put a checkball in the snout of the switch and then you don't need any wiring, but that's nothing more than someone who doesn't know s**t about what they are doing.

i have a trans out of an 84 its a 4 spd but its 2wd and has no forward gears would that valve body work???

the trans will work 100% by itself, it will go into all 4 forward gears, and reverse, just as normal. the TCC lockup kit will allow you to use the lockup converter, which lowers RPMs at cruise speed, saving you fuel, and wear and tear on your torque converter.

You don't need some elecronic POS controlling what the trans can do itself. And what do you think you need a vacuum switch for, the only one they ever used was controlled by water temp so it would not lockup until the engine was warm, which in turn would allow the trans to warm a little too.

the vacuum switch is to tell the lockup solenoid when it is safe to lock up, at high vacuum, when the engine is under a constant load. trying to lock it up without a vac switch, you may have it trying to lock when the engine is a WOT, which isnt good for the TCC.

It just tickles me that people think they need all this aftermarket BS to make such a simple thing work. He has everything he needs to make it work and needs to buy nothing PERIOD.

what got up your ass? suddenly you know it all, but your truck probably came with this setup stock, and probably never have swapped one into something that wasnt supposed to have it from the factory. i've been there, dones that, and know what it takes. sit back, and keep it down, you might actually learn something useful.

Oh but maybe I better ask for permission to say anything first since I am supposed to sit back and learn something. The only problem I have with that is, I was working on these trannys when you were still in diapers son. So don't tell me what I have to learn. And for the rest of you enjoying this little wrestling match, I am normally the most calm patient person there is, but unfortunately there are some young people on here that I really get tired of thinking they know it all and bash every idea I have. I have been rebuilding Auto trans for over 25 years now I think I have learned a few things, always have room for more but hey who doesn't. Are there any older guys on here that understand what I'm saying, if so let's hear it.

no, the excessive slippage will cause the trans to heat up. 700R4 + heat = RIP 700R4

install a huge trans cooler while you're swapping stuff over.

and that's precisely what pisses me off about you old guys. automatically assume that because i'm young, i dont know anything. sure, you've been turning wrenches for 25 years, and i've only been doing it for about 15 years now. funny thing is, i'm 24
years old, have nearly completed a degree in high performance automotive, built more cars than most guys your age have ever owned, and have helped build and maintain competition machines from nearly every form of motorsports there is.

If you have built more engines,hotrods, etc. then me (70 years "young") then you must work 24 hrs. a day 7 days a week as you have only being doing it since you were "9" years young. I have a degree in HPA also-shadetree variety.
