Is there an easy or cheap way to fix/overhaul a stuttering transmission on an older car?

Get a mechanic to check your transmission valve. He will know what and where it is. Other than that chnge the gas in your tank, it could be the EGR valve ask him Good luck!

If it is your egr valve then your car will be backfiring most likely and you can tell if it is your EGR valve by unplugging it and seeing if it runs better. If it is infact your transmission then you can buy used transmissions but they are pretty pricey.

Or poor some Lucus transmission stop slip/leak into it. Crazy nice oil that kind of works wonders on dying transmissions.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
