My 1987 300TD transmission has just started slipping when it shifts from 2nd to 3rd gear. As it shifts, the engine revs a bit and then it catches on and is fine. If I release gas while the shift is happening, it seems to work better.
Is this just going to get worse until a transmission job ?
Are there any magic vacuum hoses to unclog and have this get better ?
Any ideas this group may have would be appreciated.
