Im swapping a Carbed 302 into my F150 i know the motor will physically bolt to my transmission but how will the computer controlled 4r70w react to a carbed 302.

I have the transmission thats behind the 302 but its an aod and not really worth the extra wiring to get it right. Plus its only a 2wd transmission so id have to use a divorce case and a diaper for that case.

So if the motor and transmission dont play nice together is this something that a tune can handle?

 

You do realize that unless you do some mods, that 302 has less power than your 4.2?

 

cause im gonna put a stock motor in the truck

thanks for the answer

 

The easiest swap may be to build up an AOD or find a C6. Those are not electronically controlled.

 

Nope, I am just going to leave it alone...

Highlight and delete is my friend.

And there is the most succinct answer.

What your too good to post a answer?

Thanks for your wothless post aswell.

 

now as far as i can understand was the AOD and 4r70w were the practically. I have the transmission thats on the motor and in the truck. Its either a AOD or C6 its a 1990 F150 and via the research ive done they were offering both during this time.

so does anyone that actually know the answer want to respond?

 

Well ok then, here is your answer in it's entirety.

The transmission in your truck won't care one darn bit what you do to the engine. It doesn't care if there is an engine or even a vehicle for that matter. Why? Because it's just a dumb box that does whatever the EEC in the vehicle tells it to. It has no true control system on it's own.

So your question there is completely and totally invalid.

The correct question therefore ends up being how in the heck are you going to control this transmission when you swap to a carb setup that the vehicle computer cannot work with? The factory EEC would have a total fit with the carb engine and the missing sensors and information will leave you with a check engine light, a blinking overdrive light and only reverse and second gears in the transmission. It will run, but that will be all you get out of it. Tune all you want, the factory EEC isn't going to get the job done.

So, the obvious point here is that this is a pretty complicated swap you are looking at. One that will take a lot of knowledge to accomplish if you choose to use this transmission.

Based off of the fact that you are asking these excessively simple questions, particularly when the answer is likely not relative to the secondary question you asked about tuning, it appears that you ae going to need LOT of help.

Pay attention, if you make 'smart' posts there will be someone 'smarter' who might follow you up. There was no call for the way that you answered glc and he had a WHOLE lot more restraint than I would have in his reply to that. Which was a completely accurate reply by the way, so your answer was there even though you chose to disregard it apparently.

 

The gear ratios on the AOD and the 4R70W were slightly different and the 4R70W is electronically controlled where the AOD is not.

Again, these are simple questions. That swap is not at all simple. IF you think you are confused now then just wait a while.

Use an AOD or a C6.

If you have questions, ask them and you will likely get good answers. Part of the process is that people are going to point out the obvious first. If you want to mouth off when you don't like the answer then good luck. IT can and should be handled much differently if you are truly here for help. Biting the hand that might feed you is always a very bad idea and glc is pretty good at feeding you guys when you need it.

Im pretty sure i asked a question the only way i know how.

I didnt ask how hard the swap was, I did not ask if the 5.0 had more power than my 4.2L, i did not ask what you think of me or my swap, i did not ask if you think my question is stupid or not, i did not ask what you thought of my reply to GLC's first post it was off topic and usless... much like your first post.

I SIMPLY ASKED IF IT WOULD FUNCTION Now that you finally got off your high horse and decided to answer the question I know that using the transmission thats behind the 302 whatever it is (AOD or C6) will be easier, granted i will have to fabricate a diaper for a divorced t-case but thats not an issue.

thanks for your answer

 

Ok, so lets step back and start over.

I don't think there was anything wrong with your question(s). I didn't have any problem there at all. Questions are good.

The rest goes all to perspective. You have your perspective and I have mine. From my perspective I saw an honest answer that might not have really been relative from where you sit, but it looked to me to be to say that you may not have thought this out completely. Particularly with there was also question about a tune being a potential fix.

I obviously don't know what he was thinking and I can't speak for him, but I know what I was thinking. I was thinking that you are maybe in a little over your head here. Then I read down and saw how you replied to his comment and thought that was inappropriate.

No, he didn't answer your question right off the bat, but he also didn't answer like I would have either.

I would have said something like this.

That swap you are thinking about is going to be a lot of work and the least of your concerns are going to be on the transmission end of things. You need to start off by addressing the computer in the vehicle because that is where your real problem lies. The computer in the truck now won't be able to run either the engine you are talking about or the transmission once you put that engine in there.

Then comes the issue of getting a computer that will run the rest of the things it needs to n the vehicle and be able to work with that engine.

It's a lot to think about from front to back.

That better?

i know im over my head when it comes to this stuff, thats why i have help. But he told me to find out anything that could be useful. So thats what im doing.

I know the motor is not very impressive but it has far more potential then the 4.2L.

My ideal would be to eliminate as much electrical stuff as possible, i know the technology has its place and is very usefull but this is a mud truck so its really unneeded. Thats why I decided to go carbed instead of EFI. Someone mentioned that i need a stand alone computer, is this true, and will this help my cause they recommended baumann engineering.

 

Is this something that you are going to need things like a speedometer and tach and such? Most of that stuff is actually driven by the vehicle EEC and is going to be a pain to work around.

I say that considering the comment you made about the relatively simple, in comparison of course, wiring for the transmission being not worth it.

What about the fuel system?

I am not the biggest fan of the Baumann stuff at this time, but you are definitely going to need something to control the transmission.

I would never consider this swap for a street driven vehicle because of the excessive amount of work needed to make the things work that you would need to drive it on public roads.

Or, I may be overthinking it and it may be easier than I am thinking.

Speedometer is a must and tach is a plus. the truck will be driven on the road. This swap has been done before, and has got to be equally as technical as a Cummins swap. I have a complete doner truck. The guy thats helping me does this for a living so im not too terribly worried about it, ill swap as much from the doner truck as neccessary.
