Torque settings for volvo 740 torque converter and flywheel

never knew that a torque bolted to a flywheel, it is always bolted to a flex plate that drives the torque converter and carries the ring gear for the starter
there are washers that fit either of that flex plate or on some engines only on the converter side with the bevelled edge facing away from the plate
the torque converter is bolted to the flex plate by 3 or 4 bolts facing back to the converter from the block end
why are flywheels not used with torque converters
the mass of the flywheel affects the engine acceleration and the torque converter full of oil takes over that job so the engine acceleration would be considerable slower if both were used

Most are at about 70 to 72 foot pounds. I use locktite/threadlock on them always.

go google and type in - torque settings for (your engine as you haven't given that infomation) and there will be pages of details
There is no flywheel for an automatic. What you have is a flex plate as the torque converter acts as a flywheel

Please specify year and model of the car... I have a 1990 740 and can help you with this... I did this work for mine and the torque specs where 75 pounds. You can find more information in here: http://olybrake.com/pdf/fel_pro_torque_specs_guide.pdf

A tcc 740 is a code for a torque converter clutch problem. This is either the torque converter itself or the control part of the TCC system. dodge's have an issue with transmissions of this generation and in most cases when the code 740 sets, the transmission will need to be replaced.-------
This will help. Thanks please keep updated.please please do rate the solution positively .thank you for using fixya

need more input??sounds like you didnt locate the torque converter drive into the gearbox oil pump drive ,if this is the case scrap the vehicle .

Ok, the problem you're having is not very common however to solve this you need to replace the flywheel with the one that come with your new engine because the gears on both flywheel are different and the speed sensor will have difficulty reading the gears.Therefore the car will either misfire or not start. Did you relpace the engine with a 940 volvo 93 and up?

The belt goes to flywheel, radiator cooling fan and alternator. It does not go to a/c depending on what engine configuration.
