This is one of those videos where it does NOT go according to plan. The idea was to make a video showing how to seal up a GM TH350, TH400, or 700R4 the easy way, and how to get rid of all the pesky leaks. Of course, the transmission has other ideas. Watch all the way to the end to see what happens!

@kennydemartini2169 Год назад

AAMCO master technician here. You should NEVER use silicone on 700 pan gaskets. There's a small hole in the case right below the servo cover. The gasket has a notch cut in it to go around that hole. That hole is the exhaust for the fluid in the servo. When the 700 shifts into 2nd gear, the band applies. When it shifts into 3rd, the band releases, and that fluid drains through that tiny hole. If the fluid doesn't drain, the band will be half applied, and glazing or burning its self up. I've seen it many times where the use of silicone plugs that hole.... Go to your GM dealer, get the right gasket, it will be a black paper one like the original, use weather strip adhesive if you think it needs glued, and torque to 140 inch pounds. Problem solved.

@haleyy68 Год назад

Absolutly correct. And also on all the 1st Gen 700s they were notorious for blowing the front pump seal out. I had this happen 2 times on a new 1984 Z-28 will less than 30k miles. 3rd repair they updated the seal to a new locking type seal and never had another issue. Sold it with 120,000 still working fine.

@pentastarobsessed8427 Год назад

You should glue the gasket to the pan instead of using silicone, the silicone will allow the gasket to push out unless you allow the silicone to completely dry before tightening it all the way.

@houseofno Год назад

The moment you mentioned Facebook, you opened a whole new can of worms. Left Facebook YEARS ago and never looked back. Thanks for the video regarding the Corvette just the same. Horrible the way that shop mangled the pan and gasket. These were professionals that did this?

@gs3504 Год назад

I had a 71 Buick, I replaced the transmission pan gasket four times, kept leaking... The fourth time I just laid under the car. Finally ran my fingers up by the accumulator cover, it was wet. The o-ring was so old it had four sides! Repaired for less the a $1... No more leaks!!

@tracktoys9269 Год назад

Nice vid Ben, dealing with mine now. Mine (74) has a 400, just had to replaced the pan gasket, because my trans stopped shifting, ended up being the filter pickup tube was loose and just sucking air, no fluid getting to the case. after everything back together, like I always do left a puddle in the garage the next day. No leaks the day before weird. so when it gets warm again, I can pull it out and see where its leaking. BTW, another trick to those pans what I used to do when I worked for GM, was to get a ball-peen hammer, and with the ball of the hammer, hammer in gently the bolts holes in the pan, they warp sometimes and look like a cone.

@eddiebelvedere2400 Год назад

All good Ben. Man, I get it, sometimes the unexpected happens. You caught it, replaced the other leaks. I would like to see a follow up with the trans back in the car and running post repair. Cheers.

You have great talent and have a wonderful temperament to work on these aging cars where all the seals eventually fail. Thanks for your videos and for those that love these old cars...I had a L82 1980 Corvette auto with this bodystyle, if you live near Ben and have a job that is a bit too over your head, by the thoughtfulness of your videos, I know I would take my Corvette to you and I worked at Chevy Engineering where these cars were designed.

@kenfrazier616 Год назад

slick to think outside the box, have a funny thought my 46 chevy truck, may or might be similar, before installation I did all the seals and it haunts me again

@steves9905 Год назад

I think I have the same leak around the pump housing on my Grand Ville with a TH400. Thx for showing the removed pump...i let myself get all anxious when thinking about working on auto trans...they seem like 50 percent magic. You would think the shop would have caught that after The 2nd trip. Gotta say those collector vettes are super sharp

@briang4470 Год назад

These old gm transmissions especially the th350s love to leak, it seems like no matter how hard you try to seal it all up with fresh seals and gaskets, carefully torque everything, they still find a way to leak. Pretty much every th350 I have ever seen leaked, usually pretty bad too.

Had the same problem with the 700R4 in a 1985 C4 about nine years ago. Sadly after doing a bunch of work to that car including a new interior someone ran into the back of it and the insurance company totalled it out.

@c_firebirdgo8639 Год назад

I had a th350 that when I got up there with a borescope camera found out that it was the pump seal that was leaking. That was after trying a cork a neoprene and a rubber MSD pan gaskets

@TimTurner115 Год назад

Had the same problem out of a turbo 350. Back in 1982 Did everything you did . Still had a leak pull the transmission. Tore it down and there it was. Same problem

My best friend mother had one of theses special edition,I believe they were going for more women buyers because of the end of the C-3 and the Champagne 🥂 Colors

@operationsword9457 Год назад

Apparently the pump seal fails there due to high pressures only in that location. (Pressure regulator valve) Trans techs advise to silicone the lower pump bolts at the same location as they may leak as well. P.S. I replace all my vehicles with aluminum trans pans. More contact surface and never use cork or rubber gaskets. Steel enforced silicone or paper. Difficult to "squeeze out".

@ralphhammond8398 Год назад

Hey Ben, enjoy your videos, I just bought my 5th corvette a 77 black 4 speed , my first standard transmission and I love it. I do have a noise from the rear end when I go around a corner while taking off. I've been told that it's the clutch pack in the rear end, not familiar with that. Have you ever experienced that..? Thanks Ralph

@highwaystar8310 Год назад

With my experience with chevy transmissions the front seals are always the ones that go bad because of the heat that builds up around them.

@crawford323 11 месяцев назад

Have you ever pulled an automatic in your driveway jacked and blocked up? If you pull one, what is a newer design transmission if it is a '73 big block?

@randallorr3730 Год назад

What your dealing with there is just age and heat. 1982 was the first year for the 700R4. If you replace the torque converter seal be sure to put thread locking compound on the outer part of the seal. Those had a tendency to blow out especially when you replaced the seal. Not sure why other than the new seals might be slightly smaller. I will be honest on that vintage transmission, when they leak it usually always has to removed and resealed. The early 700s just seemed to be that way.

@kennydemartini2169 Год назад

Correct. The earlier 700 pumps need to be modified to keep from blowing the seal out. You need to separate the pump. The oil return hole in the cover needs drilled out to 1/4 inch (later ones were at factory). Press the bushing out, and use the 1/4 drill and make two notches 180 degrees apart on the inner edge where the bushing sits. Loctite the bushing and press it in. Stake it where the notches are. Wire wheel the paint off of the new seal, and loctite it in too. Get a retaining clip off a later model 700 and put it on the pump to help hold the seal in.

@clifffawcett Год назад

Plot twist! Bummer… but hey… you fixed them all now! No more leaks

@kapekodbob Год назад

Any idea why it was so brittle on the bottom ? I rebuilt my 350 and the pan did leak so I got an aluminum pan and felpro gasket. It was also leaking at the speedo. Changed it several times and realized the plastic gear had ridges than ruined the o ring so I made it smooth. It still leaks a little.

@gjjcgmail9930 11 месяцев назад

So, the aluminium pan worked out better than a steel one? Did you use a rubber Felpro gasket? Did this definitively fix the pan leak? Thanks
