Jack tilted and the transmission tipped up on its nose and transmission fluid poured out everywhere. Going around the third corner on the way home the trans I didn't want it flying around in the van and getting damaged. I brought lots of ropes and we tied the transmission down really well. I rented a U-Haul van to get the transmission. He even gave me a transmission jack that he no longer needed. The improved version with the valve body upgrades, too.

I told him I wanted to buy it and he said I could have it for free (which is what I was In the corner of his garage gathering dust. I figured he probably had the trans sitting Then I remembered that one of the guys in my CorvetteĬlub had taken the 700r4 out of his '89 Corvette and replaced it with a ZF 6 speed manual trans. I decided to buy a newer pump and just replace the pump, thus fixing the problem. GM fixed this problem by machining a lip in the pump to keep the bushing from moving. Pushing the seal with it, thus causing the leak. It seems the front bushing tends to walk out of the pump, blocking the drainback passage and The leak has really irritated me and I was tired of dealing with the puddle of trans fluid on the garage floor soįive years later I started doing some research online and I found out that there is a well-known problem with the 700r4įront pump seal that was fixed in mid 1987, when the transmission was redesigned. I decided to live with the leak because it was too much hassle to take the trans out again. Now it was leaking at the front, even worse than before and I was out $950 for the rebuild plus a lot of pain and strain getting the trans out and back in.

From mini-van drivers who park their car in the street".Īfter I put the transmission back in the car it immediately started leaking at the pan gasket, so I bought a new gasket and installed it. He said, "We've never had any complaints".

They ALWAYS leak, which I mentioned to him. The first thing I noticed was that he used a cork pan gasket.

He rebuilt it and I went to his shop to pay for it. Two of his guys came and picked up the transmission. So I went to a local transmission shop and talked with the owner. I looked at the pump and thought, "I can get it OUT of there, one way or another, but I don't think I can get it back IN without damaging something". The first step in the pump removal process is, "TOOLS REQUIRED: J-23772-A Oil Pump Remover", which of course I didn't have. I figured there are only a few gaskets involved, so I bought those gaskets from the local Chevy dealer.Īfter taking the transmission out of the car and getting it on the workbench, I opened the shop manual. Background: After I had my car for about 20 years it started leaking transmission fluid from the hole in the torque converter cover.
