Since I had a catastrophe with the black rubber Fel Pro gasket and 144 inch ponds of torque. I’m using Ricks suggestion for the Lube Locker gasket. LL says to follow their instructions provided in with their gasket, but they admit they don’t provide any. Saying to follow the owners manual.
The internet shows 13 ft lbs and start one go around at 6 lbs and the second at 7 ft lbs. My wrench only starts at 10 lbs so I’ll use my Inch pounder.
I’m very leery of trusting my torque wrenches by Craftsman but I’m not to excited about putting out more money. Anyone use this model? Any good? What is needed is a testing review on the internet.A0B8886B-3DBF-4CF4-AD13-CBD200378069.png
 
I wouldn't use a 1/2 drive torque wrench when you're only torquing it to 13 ft/lbs or 156 in/lbs. I have
a 3/8" drive beam style torque wrench that goes to 600 in/lbs that I would use for this application.

I don't think this gasket is going to as critical considering the torque value as your first rubber gasket.
I wouldn't be scared to go as high as 200 in/lbs.

BTW, beam style torque wrenches don't require calibration.
 
As usual Rick you always catch things I miss. My wrench is 3/8” drive, hence the reason my wrench has a different torque scale. I always had the unfounded belief that the beam style torque wrenches were the cheap, inferior wrenches. Can I use the wrench now that it’s 3/8” drive and be ok?
 
that's why you'll need a torque beam deflection torque wrench to check that

and having an inch lb rated one helps at times $25 on amazon

Won't he need one that goes to at least 156 in/lbs ??? The one above only goes up to 80 in/lbs.
 
I caught that already. Got one that goes to 180 inch lbs. cost twice as much but not bad
 
YES read the labels and load rates carefully
before ordering
they make inch lb, ft lb versions
1/4",
3/8"
and 1/2"
drive versions
over the decades I acquired about 6 of the different beam style torque wrenches of various types
along with several of the click style 1/2" drive versions used for main cap and head bolts
 
Dam! That expensive Lube Locker transmission gasket is leaking too. I carefully checked the pan for absolute flatness and it was great. Know I installed the gasket correctly. Torqued it correctly. In the past I over tightened one or two bolts and stripped the threads in the transmission. Since then I have been careful not to over tighten those bolts. The directions said no gasket sealer so I didn’t use any. I can only think to recheck the torque on the 13 bolts.

I was following while away.
Was Skeptical thought it would leak fail.
It did .
Junk.
 
Duraprene paper is the very best for GM Turbo 400 Transmissions with a stock car or deep truck pan.
What I use on the TH400 in my Gp.
No leaks.
Have to look up again torque specs but I recall its 9 ft/lbs torque
 
Other option no leaks is buy a Moroso Fabricated Turbo 400 oil pan and Moroso Silicon rubber pan gasket made for the Moroso pan.
It costs about $250.00.
I had on the 63 Gp when it had Olds 425 power.
Loved than pan setup.
Hung too low to clear a speed bump at my old work knocked a hole in it.
Was pissed.

Bought another new Moroso and matching gasket for.
Haven't used.

I Use a GM Stock Deep Truck pan takes scrapes better.
So far A-ok

Been through $600 in Pans and gaskets so I know what works leak free.
One New Moroso Turbo 400 Sheetmetal Aluminum Tig welded Fabricatied with silicone rubber gasket still new put away.
 
Duraprene pan gaskets used by Pro Transmission builders.
Can not buy local at the Auto parts stores.
Only Transtar, Alto Transmission racing parts manufacturer in Alabama, and Ebay sellers have them.

Believe Duraprene paper is a Alto Product.

One on the 87 Corvette 700R4 I rebuilt back in 2010 still Zero leaks.

One on the 1999 Chevy Tahoe 4L60E I rebuilt in 2018, Zero leaks.
 
the thread reminds me of a buddy who built a very impressive looking T-bucket with a 392 hemi engine, but he failed to take every factor
in the build really seriously , and think things through carefully,
and once it was completed, in original configuration, if he and a buddy sat in the seats,
he had only about 2"=to 2.3" of ground to oil pan clearance
he had to do some rather serious mods to the suspension and brakes etc, to get a reasonable 4" of ground clearance,
that allowed the car to exit the gated community he lived in even driving only 5-7 mph due to the insane speed bumps ,
at every intersection and about every 1/8th mile in the development.
he had a custom road race oil pan that was as shallow as the engine rotating assembly and oil pump allowed so he had to swap to larger wheels & tires and change the suspension.

Never trust the internet for torque specs.
Just Grumps.
He doesn't have all though.

It's in my 1970 Pontiac Service Manual.
I have all the GM TH400 Books from GMI Training in Hinsdale IL found and bought them,
