transmission question?

no!, don't change the torque converter, if there is a drain plug on it drain it but most chevy's don't have a plug to drain it so the only way to get all the fluid out of the system would be to take the vehicle to the shop and have them use the flushing machine but they then don't change the tranny filter, they just back flush it which I really dont like, the safest way to do the job would be for your husband to drain the pan fluid and install a new filter and put it all back together and have it towed to the dealer or a shop and then let them do the flushing.

If you're going to be servicing the transmission;

Some transmissions have a drain plug on the torque converter. If yours has a drain plug it's best to drain the torque converter when you do the transmission service or you will still have 3 or 4 quarts of dirty transmission fluid in the torque converter that will be pumped back into the transmission when the vehicle is started. No reason to replace the torque converter though. (AFIK). To access the torque converter drain plug (if it has one) remove the torque converter cover on the bottom of the transmission bell housing and turn the engine until you see a hole in the flex-plate with a small plug in it. continue turning the engine until the plug is at the bottom and then remove it and allow the fluid to drain. Then replace the plug.

If the timing gears have nylon teeth, you should also clean out the engine oil pan and oil pick-up screen when you replace the timing gear set.

If it's been sitting for a couple years you might want to spray some WD-40 into the spark plug holes and let it sit overnight before you start it. You might also want to drain the fuel tank and add fresh gas with some carb/injector cleaner.

Good luck!

he should change the torque converter on the transmission because the car has been sitting for a cuople of years.

Not unless he needs to. The torque converter is very expensive, and unless it has failed in some way, should never need to be replaced. It's not a maintenance item.

Definitely no need to change the torque converter, just make sure that it gets drained when you drain your tranny fluid.

No need to mess w/ the convertor.Unless the convertor seal is leaking.Draining of the convertor would mean removing the transmission...just stick w/the tranny filter & gasket.

IF A DRAIN PLUG IS PRESENT THEN DRAIN IT BUT IF NOT JUST DRAIN AND REFILL THE UNIT, CONVERTER SHOULD BE JUST FINE.

If you let your car sit for 2 years you should just be glad if it will start at all!
