To ALL forum users - As of late I have been getting quite a few private messages with questions about build ups here on the forum, or tech questions about your personal project. While I appreciate the interest, sending me a private message about these topics distracts from, and undermines the purpose of having a forum here.

During the day I wear many hats as a small business owner-operator and I work tirelessly to provide the absolute best service possible to you, our valued customer. When I created this forum I rounded up some of the best minds I knew so that any tech question you might have could be asked and answered by either myself or one of my highly experienced moderators, this way the next time this same question is asked the answer can be easily found and utilized by the next IH enthusiast having the same question.

This allows me the freedom to run the day to day operations of the business and minimize the impact to shipments and shop activities that these distractions can cause. It is of the up most importance for me to complete the daily tasks in order to best take care of you our customer, all the while providing you a forum to get the level advice and input you have come to expect and deserve from the premier IH shop in the country. So with that I ask that anyone with a question about one of our build ups or a general tech question to please use the forum as it was intended.

I am absolutely available by telephone to answer your questions as well but at times may direct you back to our website to better field your question or questions. Most other private messages I will be glad to answer for you. Thank you for your understanding. JavaScript is disabled.

Thread starter Michael Mayben Start date Jun 17, Has ordered up a "built" tf Part of that package included a request for the installation of a transgo tf-2 shift reprogramming kit.

In Jesse' thread you will see an entire valve body disassembled down to the last part. That is necessary in order to verify that the core valve body is surgically clean and has no issues whatsover.

If I'm installing a tf-2 kit into a functional valve body that is not contaminated, it's not necessary to tear it down that far for installing the system. This valve body core is a "full throttle kickdown" version which is by far the most common unit used in all ihc apps through the eop of of the '76 stuff.

Though it's entirely possible that someone has modded an earlier valve body using a "partial throttle kickdown" module. Some '77 and later sii use the partial throttle kickdown system, I have no preference for one over the other.

In the last several months, transgo has completely revamped this kit as compared to what they have supplied since or so. This kit is not designed for "ease of installation" and I'd highly recommend that it be installed only by a slushbox tranny pro that is experienced with the box.

The instructions have been majorly re-worked but not for the better! Some of the mods that were done with the earlier versions of this kit are no longer performed, instead Ihc also never used the version of a torqueflite.

Idea here is to give you an overview of what is involved in the installation of a tf-2 kit. There a few additional parts that must be installed in the transmission itself, There is much more attention to detail involved in upgrading the valve body than is covered in this short how-to But if anyone is interested in attempting to do one of these upgrades on their own, I'm willing to work with ya as always! This first pic shows the separator plate marked for attention.

There are many versions of this plate over the years!!! And you must make a positive id regarding which plate you are working with in order to perform the correct mods. The steps here involve drilling out various holes using the appropriate drill bit size that is supplied in the kit. TF-2 Install Last edited: Jun 17, Here the upper valve body casting it's zinc so ya really have to be careful here!

Then a "stop" is installed on the supplied drill bit and the stickout is set to the specified depth. This can be done with a hand drill motor or inna drill press. This is the cutaway portion of the upper valve body casting that has been partially removed during the previous operation. I do this step in a drill press equipped witha cross-slide vise for accuracy.

After the hole is drilled, the inside must be carefully de-burred. This is a component of the throttle pressure valve assembly.

That is grinding operation done carefully by hand on a belt grinder with plenty of water to keep it cool. Here you see a portion of the upper valve body casting that has had a "groove" cut in at a specified location.

Transgo advises using the edge of a file for cutting that slot, I use a carbide cutter inna flexible shaft handpiece.

This is a mod that is absolutely necessary that goes hand-in-hand with the replacement manual valve supplied in the kit. Regarding this valve body upgrade, Jesse has requested the the "shift command" feature be activated. This mod allows the transmission to be manually downshifted into any gear In other words There is an advantage or two to this feature in an offroad sitch if the driver is aware of the feature. It's saved my ass more than once onna downhill! It's best to cut this valve down inna lathe, but it can be done by hand grinding and is very time-consuming.

I grind these down by chucking inna drill motor and spinning, while using a grinding stone in a dremel. The actual dimensions for cutting this valve down are not super-critical. Here we have a comparison of the oem manual valve on the left, with the transgo kit manual valve on the right.

The kit valve is substituted for the oem valve. The differences in the lands are easily seen. Once the manual valve is installed, the rooster comb is placed back into position temporarily so that the location of the replacement manual valve can be verified and "adjusted" by bending the actuator lever if needed. Here the location of the valve lands are verified in the modded upper valve body per the instructions. Now we're gonna actually start the re-assembly of the valve body.

You must pay close attention to the instructions which pertain to the exact valve body being upgraded. There can be no debris or contamination on any part or down inside any channel. The moving parts are an extremely close tolerance fit in their respective bores and even microscopic particulate will prevent this unit from functioning properly.

I've installed a new throttle pressure lever seal in the rooster comb. Now is the time to do that. The replacement seal does not come in the tf-2 kit, so ya need to obtain a new seal and have on hand before tearing into the valve body.

Here I've re-assembled the upper half, separator plate, and lower half of the valve body, being careful to not allow any check ball to move out of position. Because I've installed the "shift command" feature, I'm gonna eliminate four of the valve body retention screws and replace 'em with the screws provided in the kit, along with installing the shift command plate.

If you do not enable the shift command feature, then that plate is not installed. This is a shot of the oem pressure regulator valve along with all new schnizz which controls the "action" of the valve.

These are the "new" parts that were not used in previous versions of the tf-2 kit. The oem prv simply uses a single spring here and has a precise adjustment spec called out which there is never any need to change. The prv retainer has been juggled into position here and the mounting screws tightened. Once that's done, the pressure regulator adjustment screw is set according to a spec provide in the instructions. This one has been set for jesses' described vehicle use, the only reason to ever change it is for drag strip use only in a full blown launch with a full race transmission The valve body is now completely assembled, the transgo brass, high volume filter is installed along with it's companion gasket.

I wash these out in the solvent tank, then they go through the dishwasher and are dried! And here's the top side of the completed valve body. All that's left at this point is to install the companion components in the transmission itself, re-install the valve body, and load it with fresh juice.

Installing Shift Reprogram Kit On A 727 Torqueflite Valvebody - Shifty Business

We've all heard of adding a "shift reprogramming kit" to our ride, but what exactly does it do inside your transmission? Basically, the main purpose is to "reprogram" the flow of fluid through the valvebody for firmer shifts and improved efficiency. It's actually pretty straightforward. Depending on the manufacturer, the kit will consist of a steel plate, some springs, and, we hope, easy-to-read instructions.
