If you know Bob, it only makes sense that he fabbed it. Gabe, I know you're a busy man, but could you snap some pics of the contraption for me? Pretty please...I'll be your friend!

there you go Bob posted for you rpm :D

If you need more, I can definitely take pics for you, will take no time..

If you want measurements, I can do that too

By the way to address the concern about the money I am investing in this build Bob

I am actually trying to stretch my dollar as far as I can.. For example I got a 2" OD band, mechanical Diode, new gearing all for so so so cheap from GPatrick ($400++ value in parts)

The valve body had to have a shift kit put in anyway.. so if I can find one that is recommended for a wide ratio , I would still rather do it myself.. if I cannot, then I will yes get lentech

The rebuild kit , I am going to shop around and find the cheapest possible, with most clutches in forward and direct drum, all else is good!

Even with Lentech, its 200 more on this transmision , but a transmission built for handeling 500++ HP , overkill.

Also talked to some people about the rear end gear ratio (mine is 2.80) which I know is HIGH. but there was mention of that hurting / balooning the torque converter. Well , I was told that if I dont put slicks on it and race it with 2.80 I will NEVER hurt the convertor.. So I can keep this gear ratio for now, till I have more money and then I will go to 3.25 or 3.55 .. But for now, the rear end cann remain as is without an issue.

I would not buy a rebuild kit based on price.  I would buy it based on what shops like Lentech use in their transmissions.  Lots of companies sell rebuild kits, but where a lack of knowledge on specifics hurts you is that you don't know for example what clutches and steels work best in the AOD, whereas a place like Lentech that's built thousands of AODs has likely tried every combination out there and uses the one that provides the best performance and longest life for the intended use of the trans.  I would research all of that before buying a rebuild kit.

 
X2 or 3 of what he said.

There’s the old saying about good, fast, and cheap!! You can have 2, not all 3!!

I agree sir

I am definitely not going for cheap as in cheapp but best for the money!!! And yes lentech is a great company I do trust. I will see what they recommend ... I did talk to PATC and they recommended one that was a bit pricey but came with hardened direct shaft. Which is again a great upgrade.

Anyway

Lowercasesteve

Oh this is just the beginning sir !!!!! ;D

alright.. just got off the phone with transgo , and realized I had tunnel vision. I was looking ONLY at the AOD-HP kit, which they DO NOT support wide ratio for

BUT

AOD-SK does! and thats awesome! So I will be able to save some money and just get the AOD-SK transgo shift kit and do it myself. saves money and works with wide ratio .and the kit is aonly around $30 !! hey thats a tenth of the full valve body :D

I may be adding to this the oring plugs to stop and prevent any leaks from the 3-4 shift valve in the valve body (from sonnax)  esp as this transmission has complains of no 4th.

thanks Gaba.......sleep will come easy for me now!

I had placed an ad on craigslist looking for a 4r70w. I got a response today from a guy that has one with performance buildup, a higher stall converter and a baumann controller setup, asking $1,200 for all of it.

This doesn’t sound bad as far as price, if everything is as stated.

Glad to hear you are making progress, Gaba. For a guy that had never changed oil before, you are moving right along!

That’s awesome!!! It’s a great price if it is as good as he says it is !!!

And thank you!! haha ... yep I have come a long way from that :D

Agreed ;) I know I will be the same at 70mpb then too like you.

I want burnouts but not as much as I want highway drive ability. 3.25 will be perfect

alright! the Transmission body is out to the cleaner to get it squeeky cleaned..

I was going to have the forward drum input shaft pushed out of the old cast iron drum to stamped steel drum from the 4R , but come to find out that the stamped steel drums are a bit less strong on that particular drum (as it comes on at the lowest gear ratio 1st gear ) and tend to come apart at the snap ring area under heavy load.. the solid drum was made available as an upgrade apparently to the 4r's that broke this. So I a deciding to keep the forward drum cast. All the rest will be stamped steel..

Tonight I take inventory then of all parts needed and make an order for the rebuild kit. :D .. this is coming along very well!

Nice progress Gabe!
I've got a couple of questions:
Were you going to have someone else separate the input shaft from the drum? If so, I did mine and it's pretty simple. I made a compressor from scrap aluminum. Easy peasy.

Where did you find the info that the forward cast drum is stronger than the steel drum? That's the first I've heard of that.

This was the transmission shop here locally

I have the clutch compressor for removing tension on the c clip and remove the piston from the drum


The shaft I was getting removed from cast drum and getting put in the stamped steel one as the stamped steel came from 4R, and the Input shaft wasn’t hollow like the AOD

Ah...ok, didn't think about The solid input shaft. The sooner you pick up a hydraulic press from HF the better. They're cheap enough.  😁
