C4 Corvette Transmission Filter & Fluid Change 

Chris thank for your excellent videos, are really useful for those of us who are enthusiasts and have a Vette. I am from Costa Rica and recently purchased a 1985 C4 with 83k miles that had been in storage for over 5 years. Your videos have definitely been very useful to be able to carry out the necessary work to make it operational. Thank you

Thanks, Chris. Another great video!

Thanks again for an excellent video! I'm about to change the trans fluid in my '90, but with a twist. I want to install a drain plug. Thanks to your video, I know exactly where it needs to go. I'm going to drill a small hole in the bottom of the pan before removing it. The fluid will drain out with no mess. After the pan is off I'll enlarge the hole and insert the drain. I like to change the fluid in the pan at every oil change, and this will make it a snap.

If you suck out the old fluid through the fill tube, you will literally have no mess when you pull the pan.

Awesome video...thank you Chris

The next owner is going to have a good car.

EXCELLENT VIDEO...THANK YOU FOR THIS VALUABLE INFORMATION...!!

Not internet hype...happened to me on my 77 cougar when I was a youngster. Changed the fluid, right after, lost the trans.

It’s about that time for me as I have a small leak at the Pan currently. Thanks for the tutorial.

Very helpful!! Great video. Thanks for your help!!!

Another nice job well done Chris. Steve

I recommend getting a Zebralight headlamp. Get the floody version. They are real bright and way better than the headlamps you get at the store. The 18650 battery is rechargeable, so you'd have to also get a charger.

Great video, thank you! 🏁

Good job Chris! I figured you’d polish the pan though. Lol!!

Nice video, well explained. Appreciate you!?

Nice...

Good job 👍🏻

I am getting ready to do this on my 85.... At 8:12, you show the O-ring stuck in the hole. It looks like a metal seal and not a rubber o-ring? How did you fish that out? Was it a rubber O-ring or a metal seal that came out?

Thanks Chris, I am planning on changing my 84 fluid soon also. How is your Grandpa doing. Take care, Jack.

When I do mine, I plan to let it sit for like two weeks so I can get as much fluid drained back into the pan from the torque converter so I'm able to change of it out. Then in a month, I'll do it again so I can try and get all of the fluid changed out. My fluid has always been pink, but I'm hoping when I drop the pan that I don't find a bunch of trash in the bottom of the pan. It's been a while since I replaced the filter. I also picked up the newer GM transmission magnet that is supposed to be stronger than the square magnet. It's round like a donut. The last time I did mine, I got a rubber gasket. As you don't have a mess to scrape off. Though I couldn't find one again and instead got the expensive Moroso reusable gasket. I like using the Scott "heavy duty" blue shop towels. They hold up and don't tear to shreds, and they don't leave behind much fibers.

My friend’s Toyota pickup transmission was destroyed by a transmission flushing system. So when my Honda van was due for a transmission fluid change the dealer wanted to do a system flush. I called Honda America they said no it would void my warranty. They said the factory Scheduled main is designed for drain and fill. The engineers know there is going to have oil residual in the torque converter.

Thanks chris😂

what filter did you use and where did you get it?

God I love that car… 😳

Excellent Video, BUT ! not sure about the use of the Jack Unit, My brother had such a unit, BUT ! after having it for 2 years the Jack Unit hose line blew out / broke, glad he wasn't under the unit. He had a tall barn and bought a regular High Lift Jack Unit.

Can you do the C5 video?

What exhaust system is that ? Looks really new

How can I drain the torque converter, Line Flush? My '74 Vette has the '86 Indy Pace Car. Same filter you demo. Is there a special tool for removing the old filter rubber grommet? The reason for asking is some AHole put water in my tranny fluid...enough said?

Just line flush from the trans return line yourself. Lube locker trans pan gasket and Dorman trans pan with drain plug.

Allways tighten bolts on valve body 😂❤

That looks like an automatic transmission. What do you do for a standard 6 speed transmission in a 1995 Corvette Coupe with an LT1 engine and I think a Borg Warner trahsmission.

What transmision is this? The automatic, 4 + 3 manual or the 6 speed

No silicone on gasket needed? And did you have any leaks days after?

what jacks are you using

👍

so I have an 87 and I am getting so many different answers on the pan torque specs from 8-15 lb you say 12 is that the same for all C4 ? thanks

Another great one. What are you using for Jack stands? And how do you get the car down after :.D

thanks for the video I like your lift was it expensive?

I suck the dipstick hole dry n replace with new fluid every engine oil change , do the same with powersteering . Oil is cheap compared to tranny repairs .

did you need to add any more fluid afterwards? Probably because the .7 was in the torque converter

I recently bought a filter kit for my 1986 transmission and it contained a rubber gasket instead of cork or paper, will that work too?

Did you put the muffler delete tail pipe on? How do you like it? Was thinking about getting one for mine.

I wish my C5's automatic was as easy for the "Drain n Fill", anyway good job Chris!

Actually, I think the transmission pan bolts are supposed to be torqued to 96 in/lbs. Luckily you didn't snap any going to 144 in/lbs.

Old oil looks like new
