700R4 Transmission - Check Ball Locations 

I was a tech with all the patches and in the automotive repair industry my entire life from the age of 13. In 2015 I found out I had a serious joint degenerative disease. I lost use of my hands for 8 months. Many surgeries later I am blessed to have use of my hands again but through being told my shoulders needed replacements , along with numerous disc problems I lost the ability to work and provide for my family. It happened almost overnight. That was seven years ago and although i am no longer doing the only profession I ever loved I found a new way to get by, God has blessed me with more understanding. I am currently building a 700r4 for my buddy's wild C10 and although it takes me ten times as long to do it I am fulfilled. God bless you sir.

@@Mike-xt2ot I have Superior 3/4 servo w/billet cover. It is larger than Corvette by far. Replace captured check valves are rear next to governor screen filter, they wear out & drop into case. Don't forget captured behind band piston. They say to use #3 easy out, but use 5/16" X 13 tap. Screws in tight, metal plate over VB to protect then pry up. Comes right out. Drill return for front pump bushing oversized, red Loctite Teflon Sonnax wide bushing in place. Stake with dull punch in 2 places rear & 2 more rear. Get a new VB Plate as they take a beating. 0.500" pressure valve, reverse update from Sonnax, use Alto Red Eagle HP kit w/ Kolene treated steels. End up with 9 friction/9 steels in 3rd with 0.28" end play. I used ACDelco 5 pinion gear planetaries front and rear. Use Sonnax HD drum, ToYo roller brg kit. Get JR shift kit for plugs, TV valve, end spring w/grooves that hold oil. If Aux side accumulator, don't forget ball, JR LU kit for VB if 87 era, choose spring for lock-up at 42 MPH. PCM / LS swap? Get 40 tooth tone ring for output shaft. 92 -94 "F" body pickup and buy connector. Run as twisted pair 9 times per foot. Either go to VSS high or VSS low. A/C syne wave changed to digital on-off signal to operate Speedo, ABS, Radio if RDS. DK, ASE master tech since 78, best of luck, sucks getting old!

@@deankay4434 thank you for sharing your knowledge. I'm doing all the steps you recommended. I appreciate you sir.

@@Mike-xt2ot There is a book / guideline laid out over 40 (?) pages that is a little dated but still help a bunch. Online, find World Wide Parts and also use the Sonnax help page. Year, make, model and it will list all parts they make, why and what the fix. I have a clip board in the garage with every instruction sheet, part numbers and I took photos during the build. You caught me off guard Will upstairs in the kitchen watching my huge 13" TV. I went by memory but look at Sonnax, Alto Red Eagle at World Wide Parts Outlet & ask for Brian, 700R4 / 4L60 3-4 power pack (057757BHP complete kit), Superior products K012, K034, and Transgo JR shift kit, Transgo SK 700 Jr-B repair kit and VB plate. I forget but I think Sonnax "Smart Shell" skip the beast, Sonnax servo release check valve (Keeps from having two partial engagements at the same time), 3- painless pistons, Borg-Warner 29 element sprag, Wide Roller Low (A74658B, A74654R) and the 85-89 700R4 has holes plugged in VB, but come out for hydraulic torque clutch. Spring selects speed. Because extra unused wires in case, I bought a nice trans oil temp gauge but used one wire (Soldered / heat shrink) to temp sensor and placed on unused bracket. Exact pan oil temp! Grounds thru case, wire gauge where you want it. I used a cooler but temp controlled fan. Bought $6 digital C/F controller, runs relay, turns fan on or off as I stuck a skinny A/C condenser from import under bed. No hoses to radiator or front. Metal shield with louvers grab air behind cab under bed but over exhaust. Using buckets so built a console from CPVC from Home Depot, wrapped in leather and placed controller at back. PTC thermistor in metal can shoved into the inlet fins of condenser. Compression fittings to hose to trans. I over think things but research and plan. Keeping paperwork, notes and list of brands and p/n's on sheet for future service. Look online for PDF of automatic transmission service group as it covers 700R4 / 4L60. If running 400 HP to 600 HP trans, keep it cool with wide band on 3rd, last for decades. Driver not a racer and still 1/2 cost of standard Raybestos built trans. DK.

Im sorry to hear about your pains I know what pain is and I got healed amazingly in Jesus name and I learned by his stripes we are healed and Ive been working on my 700r4 recently and appreciate all the tips and advice, but I want yall to be healed too so I say right now BE HEALED IN JESUS NAME NOW! RECEIVE IT, and if anyone here is a non believer thats alright Jesus heals them too because thats his will and nature so receive it and believe. BLESS Yall

I love this guy

A good question, I also would like to know the answer. Outstanding videos Hiram.

I Did That In A 1988 Vandura 5.7 350 Tbi And Seems Like It Takes A While For 4th To shift but Didn't Really Notice Any firmer Shifts That's All In The Spring And Preasure.

This is the same transmission that has a AUX valve body. The aluminum housing is the forward accumulator with the check ball. Only pressure switches, wiring for TCC lockup is different and some have a temperature snap switch mounted on a bracket. The 1993 is the split in spool valves or full ECM controlled transmissions. So the same as yours. Two strategies are used with the temp switch. One allows TCC lockup only when warm enough, the other keeps you out of 4th gear until warm. Yours will very! My 86 GM shop manual for the Monte Carlo, El Camino, etc., has 9 different wiring schematics alone. Hiram is a busy man, making money for himself and family, as techs fight the clock, so he does not answer most posts asking him to fix their tranny. I don’t blame him, but admire the time he does take to video his work! ASE Master Tech since 1978-Retired

It's recorded ; rewind the video or slow down the playback genius.

Oh yes, being an ex GM dealer tech, I've driven late model vehicles the way you described in your reply many times. The 2010 Camaros were particularly fun to do that with, even the ones with the V6 :) Don't really know anything about the 200 series, mainly because of exactly what you said. They had such a short run on those. Definitely gotta agree with the engine and trans having to be in perfect harmony with each other for good overlap to take place. The GMC Acadia is a good example of this. There's only one sprag in the trans, so it's as close to a true clutch-to-clutch trans as you can get without it actually being one, so as you know, shift timing is tricky to pull off seamlessly. As a result, anytime you have to reprogram the ECM for whatever reason, the TCM must also be programmed at the same time. The opposite is also true. Anytime you have to reprogram a TCM for whatever reason, the ECM must also be reprogrammed.

Look on part 2 of the 700R4 rebuild video. Search on my channel and scrol to the valve body sección.
