I want to build.....

......a full manual, reverse pattern "race" IH 727.

This will be going in a lighten sii racer, 392 in front (pretty much stock, rebuilt and strong) with a possible much more built mill in the future. D20 will be hanging off the back, racing ratchet or gate style shifter.

Use will be short-track tuff truck style racing, probably some mud drags and hopefully some longer "desert like" stuff down the road. Constant on-and-off the throttle. Ridd'n hard, put away wet. I think I want full compression braking in all gears, but not 100% on that. It will also probably see some occasional trail riding and recreational dune running.

I plan on taking one of my "junk yard" 727's I have laying around (of unknown condition), doing a complete rebuild, and installing the parts necessary to get what I want.

So I need recommendations:
rebuild kits - best bang for the buck while not sacrificing quality.
Tb replacement - again, best bang for the buck while not sacrificing quality.
Mod/replacement recommendations while I'm in there - (vents, sprags etc)


I don't have a ton of money to sink into this. But my last tranny was a "jy" 727 behind a tired 304 that I did nothing to other than keep topped off in fluid. It got the job done but I have my suspicions it really helped the 304 be a dog or atleast wasn't doing me any favors. With this race truck v2.0 I'd like to but something a little more known back there.



If I lived closer to mayben I'd probably sweet talk him into atleast walking me through one or begging, pleading, guilting (or bribing or trading) him into building one for me, but alas the distances are to great. Rick pratt and snohomish transmission isn't too far from me, but even with any sort of "old club" or "friend" discount, he's too expensive for me. So I suspect I'll be doing this myself in the garage. Oh, ya, this will be the first auto I've been into. I've been told it isn't rocket science. Just keep things clean, and put them back in in the correct order.
 
What's your timeline on this Mark? Mayben and I are in the process of a video series on 727 overhaul. 3/4 of which is in the can...only 1/4 has been edited. If you're not in a tremendous hurry, the whole shiterree might be done in time. Of course this is not meant to take the place of a 727 bible like the monroe book and/or a service manual, but rather to serve as a fairly detailed a/v supplement. While it wouldn't delve into any of the "purpose built" mods you have planned, it will cover basic overhaul procedure which is a big part of what you'll be doing.
 
Get the munroe book Mark and memorize it.

From this point going forward, all my 727 builds are using master kits from B&M.

If you are sure you want the reverse pattern schnizz, then use a transgo tf3 kit and be done with it.

A bolt-in sprag is a method for saving a case that has had the outer race spun. It adds no strength to the tranny and is a waste of $125 in my book.

These units are far stronger than any IH pumped up motor is capable of breaking in stock form if a shift kit is installed. The B&M components in a box are a great value using premium materials. Most all the "information" you see on the 'net is in regard to mega-horsepower motors and drag race shit. No need for all that crap in what you are proposing, a total waste of cash.

First race I'm going to try and hit is May 22nd. I would really hope to have atleast a month of running, shake down and learn to drive (again) before that.... But I say that everytime and them am busting my ass the night before just to get it loaded :d

right now its a pile of parts, a new frame I've started, a plan in the head and my old truck beat, broken and done sitting on the trailer (still) outside. In theory I have plenty of time... In reality, well family, work and a million other projects get in the way :d

if worse comes to worse I toss in a tranny I got laying around and see how it runs, its not like I don't have any "spares" to rebuild and swap it with later :icon_rotate:

Good info Mike. There are so many kits out there its nice to get a recommendation from someone thats put one or two in :d. I'll check out the transgo vb. 99% sure I want the rmvb, if not, it can always be changed.

I read your opinion on the sprag in another thread and will follow suit. I'm aware these tranny's are plenty strong, so I was pretty sure I didn't need to beef it so much as pick the right components to get what I want. Hmmmm, maybe I need to get Jeff to sponcer me one of your rebuilds :icon_idea:, I'll toss in two cores and pay for some of the *bling* parts, and give him some sticker space :cornut:
 
Mark,

if it is a serious wheeling rig, you want the rmvb. I loved it in rockscout and if I build a rig for wheeling with an automatic, it will have one. Easy to drive and easy to use.
 
Having followed a ton of builds on other boards for go fast/competitive stuff... He is my $0.02:

a) use quality stuff and replace everything at once
b) triple check everything when you build it
c) run every test possible before installing it
d) check everything again when it is installed
e) run a huge cooler with big lines and its own fan

if you follow all those things you should avoid 90% of the problems I've heard of people having with offroad/race automatics.
 
Back to the top.

As I suspected, nothing has happened since I started this thread. I have missed every race that I've known about and wanted to make do to one reason or another (besides no viable, "running" rig right now, still toast after last years naches beating), but mostly do to every event date has had a [more important] Family function date that coincides.

However this is still on the burner, and I think might get bumped up in priority soon as I'm tired of not having a running truck right now. (finish 4-year deck project and then I'm good, and I can see the end!).

So..... Hows this project coming along :d :thumbsup:
 
I will be doing a manual valve body (reverse pattern) soon for pink, a complete "how-to" will be posted once it's done. This will involve the installation of the transgo tf-3 kit.

It's actually little different compared to installing a transgo tf-2 kit or the similar item from B&M. A few different parts and a few different processes.

B&M does not currently offer a full manual shift/reverse pattern valve body kit for a 727.
 
Well now, if your already building one for monte... Why not two :d


whats the differance between the tf-2 and the tf-3 kit?? Their website is almost usless, they have different descriptions, but essentualy say/do the same thing.

The tf-2 kit is suitable for any use. It has all the advantages the re-programming provides, but maintains the oem shift pattern and full automatic operation if the stick is in "d". If...the "shift command" feature is enabled during installation of the kit, then the operator can stick it in first gear at any speed...ya can imagine what a cheep thrill that can be but there are some advantages to that feature inna serious trail rig.

In my opinion, the tf-1 kit is worthless, I'd never advise spending money for that, too much trouble for not enough bang.

The tf-3 system totally eliminates the ability of the transmission to operate in an automatic mode. It must be manually shifted, both up and down. You can roll to a stop with it in third gear though and then shift down to first after stopping or slowing way down.

The tf-3 also reverses the 727 standard shift pattern so a ratchet shifter can be used. That stuff was all developed for the drag race crowd and has been adopted to a degree by the off-roaders also.

So...using a stock Scout II shifter, the "normal" drive position becomes 1st gear, then as you pull back ya hit second, then third.

Plan here is to have an "early" 727 valve body with a tf-2 kit or the equivalent B&M item (I have no preference of one over the other now) on the shelf and ready for exchange. If a "late" valve body is needed (part-throttle kickdown), then those will be assembled to order on either a customers valve body or core units I have available. The tf-3 kitted valve body will be built to order, the actual market for that item is non-existent so it doesn't make any sense to have one sitting on the shelf.
