700R4 Transmission Valve Body - Transmission Repair - Transgo Kit Install
This is a video of a THM-700-R4 Transmission. It is very common that after
you get done with one of this units, it will not want to upshift into 4th
gear. My repair kit of choice for this unit is a Transgo kit as you see
here. There are different types and brands of valve body kits on the market
and they all work very well. If you notice, this is not a high performance
kit, it is designed to take care of some of the factory flaws and normal
ware that you may encounter on the bores and springs.
Transmission repair is a vey fast paced line of work and the use of this
kits is very helpful at times since it takes the guess work out of the ones
that decide to give you some trouble. Saving you time and getting it out
the door quickly to work on the next one.
700R4 Torqe Converter Lock Up Wiring
I've learned a lot over the winter rebuilding my Chevy automatic
transmissions. Thanks a bunch to Michelle for letting me take over the
basement all winter and putting up with the musk of burnt tranny fluid. I
feel much better about my automatic Astro van now, knowing I can fix the
transmission, should I burn it out. Before it was like "when's this trans
going to go?" and I would always be on the look out for a new van, or have
a back up truck ready to go. Now I will have a back up automatic
transmission built and ready to install.
I didn't really film the rebuilding, cause honestly I didn't know what I
was doing, and it took about 6 months, hour here, hour there. Next one I
will film, with short cuts, to show what you most likely get with a $800
I did a few mods to the automatic transmission to make it hold up better
towing the 4500lb electrical trailer. Those mods are going to cost me more
work on the install, because I will have to mess about pulling the
governor, and modifying the governor, to get the shift rpms back to where
they were before the higher pressures and bigger valves. I have 2 videos
covering the mods I did here.
My start at being my own transmission mechanic, hasn't gone well. I tried
to give a little more life to my old transmission, by giving it bigger
serveros, to put more pressure on the burnt clutches. I screwed that up,
it was very difficult to get the servo in, wile the transmission was in the
van. I have now "sanded out" the damage I caused in the servo bore, and
put the original servo back in. The new servo will just be in the new
I will now ride out the transmission in the van, until I lose third and
fourth, next spring or summer I am hoping, or maybe when I get my garage
built. (I now have spousal permission to build a real garage w heat :-)).
I got an 84 transmission, that also needs a rebuild, for $100. The newest
transmission I can use is 92, and that's 20 years old. I figured I would
rebuild whatever I get. There is too many scammers out there that want
$1000 for their "rebuilt" transmission. Most of them haven't even cleaned
the thing, what is to say its "rebuilt", and its not rebuilt the way I want
So this is a video of the servo screw up and the start of the rebuild of my
84 transmission. Parts are on there way. Although the 85-92 trans was
better than 84 this one will be built for towing, and a future diesel
conversion, better than anything 20 years old.

GM 4L60-E Transmission Re-Assembly (Rebuild) - Transmission Repair
On this video we go through the re assembly of a 4L60E Transmission. I
tried to make this video shorter for you so I skipped the bushing
installation and installing the bolts on the valve body. But you can go to
the teardown video for reference on where each bolt goes, since they're
different sizes. I will make a follow up video on bushing installation.
700R4 Transmission Governor
Basics on how a transmission governor works. The large weights on the
outside control the low speed shift, the lighter inner weights and springs
control the high speed (WOT) shift points. Ligher weights will move your
shift points to a higher rpm. As the governor spins, it forces the weights
out, which moves the plunger up toward the gear, changing the flow of fluid
to shift gears.
Automatic Transmission Rebuild Part1.wmv
My second Chevy automatic 700R4 transmission, bought strictly for one part,
the rear sun gear. The rear sun gear in my first rebuildable core has a
broken tooth, and potentially ready to break off the rest of the teeth.
The rear sun gear is obsolete in the pre 86 Chevy transmissions. That
means I have to buy a whole new sprag and gear assembly, for only $200. I
knew I could buy another "core" transmission for $50. Life threw me a
curve ball, and sold me a Chevy diesel motor, torque converter, and good
700R4, for $300. Best deal I have found in forever.
A quick vid today is a look at the inside of the automatic transmission. I
will do a video of the pump modifications I do, and some random portions of
1-2 WOT upshift too high 2-3 WOT upshift too low.
