Vibration, Clunking noise, starter not working correctly.
loud rattling noise when idling.
If it really IS the flex plate, that's a lot cheaper than other problems that could cause a bad knock. The flex plate is a steel plate that bolts to the rear of the engine and has gear teeth around it. The starter engages with the teeth to start the engine. The torque converter also bolts to the flex plate. All power produced by the engine that is used to move the vehicle goes through the flex plate. Flex plates get old and sometimes crack. When that happens you want to get the old flex plate out of there as soon as you can before it breaks completely and destroys the torque converter. A flex plate is relatively cheap, compared to a complete engine rebuild or replacing the torque converter. To replace the flex plate, simply pull the engine (or transmission, whichever is easiest), unbolt the flex plate from the crankshaft, bolt up a replacement and put the transmission (or engine) back. Of course, there is more involved than that, but it's not as bad as some repairs.
Probably a bad flex plate and ring gear.
Static ______________________________________________________________________ Rattling is not a usual complaint for a transmission. Cracked flex plate, loose bolt holding the flex plate to the torque converter, spider gears going bad. Does it all the time or only when moving? Starter not disengaging all the way and catching the teeth on the flex plate. Hard to know without hearing it.
A automatic has a flex plate and a tork converter.. A manual trans has flex plate and fly wheel...
remove engine or transmission replace flex plate (flywheel).
Yes, a 168-tooth flex plate can work with a 700R4 transmission, provided that the engine it is mated to is compatible with that flex plate. The 700R4 typically requires a specific flex plate to match the engine's starter and flywheel specifications. Always ensure that the flex plate is designed for the engine and transmission combination you are using to ensure proper fit and function.
To my knowledge the only small block flex plate that doesn't interchange is the small block 400.
your spacer plate and starter should be the same the flex plate and converter will need to be replaced
the purpose of the flex plate is the same as a flywheel. when the starter is engaged, it spins the flex plate, thus hopefully starting the engine.
You Have to pull the transmission or at least pull it back so you can reach the bolts holding the flex plate to the crank.
You have to pull the engine or transmission. The Flex plate is at the back of the engine on an automatic transmission. 6-8 bolts hold the plate to the engine, and four bolts hold the plate to the tranny.
