700R4 build thread.

Torque ALL Valve Body Bolts, 1-2 Accm., & Aux. Valve Body Bolt to 8 Foot Pounds (96 Inch Pounds), A Inch Pound torque wrench is best, Foot Pound are not very accurate in the lower scales.

Tighten in Sequence!!!

Install Manual Detent Spring, Torque the bolt to 18 foot pounds.

Lock-Up wiring.....WITHOUT CONVERTER SHIFT VALVE in the Valve Body!!

The easiest solution is to stack Lock-up on top of the 3-4 Shift with the 4th gear pressure. You will need a N.O. (Normally open) pressure switch installed in the 4th gear oil port in the Valve Body, The Switch you see in the above pictures is where the Switch goes.

Bowler has a "Time Delay" TCC module that works very well in Swaps. A Vendor here is selling them at a good price http://67-72chevytrucks.com/vboard/s...d.php?t=611898
Comes with a New harness, 4th gear switch & Dual Pole brake switch, Keep that in mind when you perceive the price to be high.

Install the transmission Filter, SPX Filtran is highly recommended, Delco Filters are Filtran.

Install Trans Pan Gasket & Trans Pan. Cork & Rubber gaskets LEAK!!
OEM Gasket, AC-Delco part# 8654799.
The Bowler TCC kit comes with a OEM style Gasket.

Clean & Place Magnet in Trans Pan.

•Tighten the bolts alternately and evenly to 8 Foot Pounds (96 Inch Pounds).

Extension Housing/Tail Housing.

Speedometer gear selection. http://www.transmissioncenter.net/sp...__va.htm#700r4

Install Speedo Drive gear on Output Shaft If replacing. Note the Color you have when searching for Driven Gears & Housings.

Replace Bushing, AC-Delco 24241501 Teflon coated Bushing.
Aftermarket Brass are OK to use.
Stay away from the Aluminum ones!!

Install Output Seal, Coat the outside diameter of the seal with Loctite.

Install Tail Housing to Case seal on the Housing. It is "square cut" be sure it's not "rolled"

Install Tail Housing, Torque the Four Bolts to 25 Foot Pounds.

Install Speedo Driven Gear & Housing.

Governor.

Let me start out by saying.....Stock V8 700R4 Governors are calibrated to hit "High Gear" as soon as possible for MPG & Emissions reasons, Corvette & F-body Light Weight Governors being the exception.
But they have there drawbacks as well like "Floating the Valves" on a WOT 1-2 shift on certain engines.

I have found that using TH350 Governors are a good compromise, New NOS ones can be found on E-Bay.

TCI & B&M sell Governor Calibration kits, If you wish to go that route.

**Tuning with TransGo Governor Springs**
These are Combinations I find to work well.

Earliest Shift to Latest Shift....

Red & Yellow
Blue & Yellow
Red & Green
Red & Black
Blue & Green
Red & White
Blue & Black
Blue & White
Yellow & Green
Yellow & Black
Yellow & White
Green & White
Yellow & No Spring

The Green Governor spring comes in TH350 shift kits, It is modeled after a Stock Green TH350 spring.



Inspect Governor Gear for wear.

Make sure the Governor Valve has free movement, Hold the Weights closed & shake the Governor, The Valve movement should be audible.

Insert Governor in it's bore.

Install the square cut Cover seal on the Governor Cover.

Install Governor Cover, Do Not Use Silicone, That seems to be a thing for people to do....It's not needed.

[clinebarger]

TV Cable Seal Installs in the Case First! Then the Cable Housing.

Install Dipstick Seal into Case.

Double check that the Turbine Shaft Seal is in place, Lube it with some TransJel before installing the Converter.

A Dry 700R4 with a Stock Diameter Converter takes 12 Quarts of ATF, Pour 7 quarts in, Start the engine, Then pour the rest.

That is pretty much it. You can post Questions &/or Comments now.

Just for clarification as I'm hooking up my switch, the stock orange wire goes on same side as lock up wire and stock white wire goes opposite, correct? Also can I use the spade next to white wire to use for brake controller? Thanks, getting close to firing. Mike

edit: I was refering to pic in post 134 but pic didn't crossover. Mike

Hi everyone, new member from Aus.... I hope I can pick your brains straight up, i am putting a transgo sk700 kit into my 700r4 and i have hit a snag..... the 2-3 shift valve and the 1-2 low range valve will not remove from the valve body.... i have removed the pins holding them in bit they still will not move, in or out or twist.... any ideas? and will it cause any issues if the rest of the kit is fitted and i leave those two valves as is?

Oh and i have read this thread and great info thank you

Regards

Do NOTHING with the Orange or White wire, Those are for your brake lights. Just plug the original brake switch connector onto the two pins closest to the Plunger.

The 2 pins furthest away from the Plunger are what you need too wire up......
Ignition Power too 1 pin, Lock-up solenoid power wire to the other.

The Lock-up Pole on the new brake switch works opposite of the Brake Light Pole.

What year Valve Body are you working on?? If it has a 2nd design/Combined TV & Low bushing, Leave the shift springs alone.

The SK-700 (Green Box) is for Type 1 VB's, SK-700JR is for Type 2 VB's.

But, Too answer your question.....
Try pushing on the Bushing, The Spring pressure will generally push back on the Bushing, Do this back & forth til the bushing loosens up.

If it's really stuck, Take a Pocket Flat Blade screw Driver or an Awl & lightly pry on the Valve in the Bushing, Once the bushing starts too move out, Use your thumb to push the Bushing back in....Repeat til the Bushing frees up.

Welcome to the board!

Thanks for the reply. It is a late model trans, we never got the early version as our vehicles didn't get the t700 until 1989-90.. my understanding from transgo was the sk700 kit covered both versions and the jr kit only the late. The sk700 kit refers to both early and late models, correct me if i'm wrong but the sk700 kit comes with parts to update the early version? Where the jr does not.

I have tried prying it out but no luck, as you recommended leaving it if it is the late model i will do that. The trans is going into a 1976 corvette I built from the ground up

Trans-Go needs to revise that because the SK-700 doesn't work very well on Type 2 VB's. There are several different size Shift Valve TV Bushings.....Their "One Size Fit All" Shift Valve Springs flat do not work well on Type 2 VB's,
The Line Bias Springs (Purple & Skinny White) are also wrong for the later style Line Bias Valve, The "Red" spring in the 700JR is perfect.

The Most Important part of either kit is the (Bootstrap) TV Valve Kit.
