To find the precise number, you would need to:
* Consult a repair manual: A factory service manual for your specific year, engine, and transmission will give you the most accurate information, including diagrams showing bolt locations.
* Look at your own vehicle: With the transmission accessible (after disconnecting everything else, of course!), you can count the bolts yourself.
Trying to guess based on general information is unreliable and potentially dangerous. Always use a reliable repair manual for accurate information on any automotive repair.
