Hey guys, I have a th350 and I'm putting in a hughes 3000 stall converter. My question is, how many quarts of trans fluid should I buy for the converter and trans pan? I'm going to service and change the trans filter also.

A bone dry th350 will hold 10 qts. with a stock size converter. The converter holds 4 qts alone. So I would buy 10 qts. might save you another trip to the parts store for more fluid.

Thanks for the info...How much fluid should I put in the converter on the install? I know not to install it dry

Must have a big old cam to need 3k stall.

HEHE, Well, it's not a super huge cam, but it has a nice lope. It is the Comp Magnum 270, flat tappet.

If its the same diameter as a stock converter start with 3. It won't be as messy installing it full. 5 qts in the tranny to begin with. That leaves 2 or less to bring it up to full after it gets warm.

Thanks for the info...Are there any tricks to installing a TC? I've researched the forums and it looks pretty strait forward.

For the love of God, YOU HAVE TO MAKE SURE IT'S ALL THE WAY ON!!!

Madmax...you don't anywhere near a 3000 stall TC for a 270 mag cam, a stock 1600 - 1800 TC will work just fine.

OK, Well in searching all the forums and input from from the guy's here, they all have recommended a 2500-3000 stall.

Place it on the transmission input shaft, push in with moderate pressure and turn it clockwise until it clicks into place 3 times. Sqzbox is right on the money with quantities.

[Madmax305]

Thanks for all the input guys....This will be my project for next week.

A 2800-3000 stall is just right for the 270H magnum cam.

A "stock" converter (the 12" 2000 stall) will work but the acceleration will be
a bit lame compared to a 3000 stall.

A "stock" GM 13" converter will be too low a stall and can/may result in idling issues when idleing "in gear" as well as lame initial acceleration.

Do not combine the high stall converter with a hiway gear ratio. Like 2.56:1

The only things you have to watch when installing the new torque converter is to add at least 1 quart of auto trans fluid to the converter before install and to make sure the converter is seated all the way into the trans pump and correct torque converter bolts are used to attach the converter to the flex plate.
A good time to inspect the flex plate and ring gear (welds) as they are often cracked between the flywheel bolts.

1qt. in TC, 4-5qt in pan, start engine, shift thru D 2 1 & R, add a qt. or 2, check & fill to full. If you have the vehicle on jackstands make sure you stop the wheels before shifting from D to R.
Trans Capacities >> http://www.tciauto.com/Products/Tech...d_capacity.asp

From TCI's FAQ Section:
You should have 1/8" (.125") to 3/16" (.1875") between the torque converter and flexplate before pulling the converter forward and bolting it to flexplate.
--------------------------------------------------------------------------
You can use a straight edge, laying it across the face of the bell housing. (Engine side) Then with the converter installed in transmission, take a ruler and measure the distance from the straight edge down to the mounting pad of the converter.
The measurement should be as follows:

GM Turbo-Hydramatic 4L60 1 1/8" from Bell housing to Pads----------------
GM Turbo-Hydramatic 4L60E 1 1/8" from Bell housing to Pads---------------
GM Turbo-Hydramatic 4L80E 1 1/8" from Bell housing to Pads---------------
GM Turbo-Hydramatic 350 1 1/8" from Bell housing to Pads-----------------
GM Turbo-Hydramatic 400 1 3/16" from Bell housing to Pads----------------
GM Powerglide 1 1/8" from Bell housing to Pads----------------------------
Ford C-6 1 1/8" from Bell housing to Pads---------------------------------
Ford C-4 1 1/8" from Bell housing to Pads---------------------------------
Ford AOD & AODE 1 1/8" from Bell housing to Pads-------------------------
Chrysler Torqueflite 727 1 ¼" from Bell housing to Ring gear (NOT PADS)----
Note: Distance may vary either way .050".
-------------------------------------------------------------------------
You should inspect the old converter you are removing for damage to the converter hub that rides in the pump of the transmission. If you find any wear on the hub at all, you should replace both seal and bushing. If you find no wear at all, you may be fine with just a seal replacement. You should at least do one (seal) if not both. (seal & bushing)
