What brand tranny fluid do you run?

How many quarts will I need to get for my converter swap?

 

I used Castrol 10w30.

Kidding. But it was Castrol Dexron.

I wound up having to add about 6qts or so. I lost some here, some there, what was in the old converter.. it wasn't terribly messy, but that much caught me by surprise.

 

I'm looking for the amount needed to flush the whole tranny and converter. That has to be more than 6 qts.

 

I'd take it somewhere to have it flushed. Your looking at a minimum of 13 quarts. I just had mine rebuilt and it took 12 quarts.

As for fluid, I called a couple shops and they both recommended Penzoil ATF. DO NOT USE synthetic oil in the trans. The trans needs friction to work properly.

 

I second the statement against using synthetic fluid in the trans. I use Valvoline Maxxlife in mine, works great. Also you don't have to have an old trans with lots of miles on it to use it. The converter and shiftkit install took 12 quarts, get 13 just in case!

 

I guess I missed that in your first post.

Obviously in that case it is more than 6qts. As mentioned, anywhere from 12 to 13 qts.

 

I'd like to hear WHY one shouldn't use synthetic in the M6.

I followed the guide on Brent Franker's Page, and I just have trouble believing he would steer someone wrong.

 

I doubt he would either but try and call a tranny shop and ask them. Let us know what they say.

 

Synthetic is fine in the manual. It's too slick for the autos though, and can cause some sloppy shifting. For instance, when I still have mobil 1 ATF in my auto, it would bang the rev limiter on the 2-3 from time to time. With nothing other than a switch to Maxxlife I never had that happen again.

 

LOL! Well, I'd never try to steer anybody wrong.

However, I do use synthetic in my completely redone 4L60E too. No probems yet

 

For non-synthetics, Mobil Dexron III, AC Delco Dexron III, and Aamco Dexron III. For synthetics, Amsoil and Redline. These are the best from what I have seen over the years.

 

I just did my TC swap a few weeks ago...

If you are flushing the whole system you'll prolly need about 12 quarts, but if you are just draining the pan and swapping the TC, you'll only need like 9-10...

I first drained my tranny by droppin the pan, then hooked it back up and dropped the tranny. Took off the old TC and threw it aside. Then put about 1/2 to 1 whole quart of fluid in the converter to "prime" it...

put it back on the tranny, reinstall the tranny, etc...

Then pour about 6 quarts down the dipstick tube.

Lower the car to the floor if you haven't done so already and fire it up... then slowly run through each of the gears, leaving it in each one for a few seconds to let the fluid flow through...

Then add fluid as needed. Prolly 3-4 more quarts depending on if you have an auxillary cooler or not...

Every time you put a new quart in, run through the gears, and let it sit and idle for a couple of minutes, and then check it again...

I used Valvoline MaxxLife in mine...


Since you'll be dropping the pan, I recommend you get one of these...

It'll save you lots of time and a big mess down the road. Not to mention, if you ever overfill, it's easy to let a little out...

Also, might wanna grab one of these too...

The gasket is a thicker synthetic compound that can be reused, and seals much better than the ****ty cork gaskets that come stock...

 

I got the GM truck pan that some guys use since it's deeper than the stock 4L60E pan. The truck pan part# is 24215535. I assume the TCI filter and gasket kit you showed me http://www.jegs.com/cgi-bin/ncommer...amp;prmenbr=361 can be used with this pan also since they have to be the same bolt pattern, correct?

 

yes, as long as you have a 4L60E, the gasket is made to fit the trannies bolt pattern... As long as your aftermarket pan has the same pattern, you shouldn't have any trouble at all...

 

Synthetic atf is made with friction addative's that will give you a quicker and a stronger shift. They didn't make it not to out perform standard atf .
