Hi!

Can anyone help me with my transmission? I own a 1991 galant gti which was converted to a automatic transmission. Had problems a few months ago when it stopped shifting. I went to a surplus store and bought used auto transmission. However, i experienced problems with the one installed encountering not shifting and downshifting. So i told the shop to replace it. Apparently after replacing it for five times its still the same. it would shift for a while but after running for sometime it would go back to the same problem. we already tried changing the computr box and valve body. Im getting so frustrated. Maybe someone can help sheld light on this matter
