4.7's and a AW4

I just got back from my week at Nascar. It's the first time out with the trailer and my new '17 stroker. What a dis-apointment, it's faster than cr** by itself, but with the heavy load the AW4 shows it's late/soft shifts. I have seen only one company that list performance transmissions (2500$) and I was thinking of a "shift kit" as they are much more common and I would be interested in what gains I would receive. It's a 2k, btw!

Re: 4.7's and a AW4

Recently we put a Trans-go kit in my AW4,trying to improve the shift firmness and 1st gear lock. Thought I bought all the necessary valve body gaskets..but the kit did NOT have a gasket that was a perfect match for MY valve body type. Because the gasket was not a perfect match the line pressures low.After putting the old used gasket back in the pressures were back to normal and the trans shifted as expected,,,but, reverse was very weak.
It was decided to pull trans and replace with a low mileage stock trans.
The old trans was a new factory unit put in ,,,,,,,,,,,,,,,in 08 for the trip to Moab,so it was 10 years old and was fine until the"up-grade"
YMMV

Re: 4.7's and a AW4

I recently put the trans go kit in mine. It was a used trans after my 290k one exploded. It's a trail rig so I did all the hot rod shifts. Other than a rather critical washer fell out of the pressure regulator valve that required me to pull the valve body back out it works good. With the hot rod shifts it's a pretty much instant 1-2 shift and the others are very firm. For a street rig I'd probably do the truck shift mods but up to. It does not come with gaskets. They have a kit you can order but I ordered some off rock auto that fit correctly.

Re: 4.7's and a AW4

I ordered the HD-2 kit last night. When it gets here I'll spend my time going thru the instructions.

When I had got my stroker on the road I had soft shifts when towing my boat. I adjusted the TV cable so itís a little tighter ( the trans sees that I have my foot in it more ) and it shifts tighter. I havenít seen any adverse effects as of today and Iíve been running it like that for about a year

Re: 4.7's and a AW4

The shift kit does do wonders for quick and firm shifts. However, the TCM shift points still suck a big one.

Re: 4.7's and a AW4

I find it almost unbelievable that there is no support for the AW4. At best is the connection to the A340. I tried to find a good torque converter, I called Hughes today since their local and I've used them many times before, Nothing

Re: 4.7's and a AW4

We ran the HD2 on 4643 and it was outstanding.

I've been trying to figure out if we can intercept the VSS signal and tweak it to raise the shift points (-10% or such similar to speedo adjustment), but haven't put in the leg work yet.

Re: 4.7's and a AW4

VSS/OSS is just a hall-effect sensor, not going to be able to speed up the signal any without making the output shaft spin faster. You should be able to generate a separate signal though. Seems like a lot of work for small gain but its possible.

Better to do a fully programmable TCU and make your own damn shift tables -- https://www.powertraincontrolsolutio...on_Controller/

Re: 4.7's and a AW4

Why not just put the "wrong" speedo gear on it to make it think it's going faster/slower?

Re: 4.7's and a AW4

I went around the corner to my transmission shop! Since I only have the use of one hand I figured this might be a good one for the pro's. He gave me a shitty price on just a "valve body" shift kit install, he gave me a good price on a "complete" rebuild with HD parts, something I might consider!

Re: 4.7's and a AW4

I received my Transgo kit today. I've been reading, reading, and re-reading, unfortunately I won't know which valve body I have until it's taken apart. As far as "port" drilling, I'm thinking about 70% of their recommended sizes!

AW4s have the Type-1 body
