My son has a 1999 4cyl Honda accord. Timing belt was changed at 130000 miles---It has a loud noise after 40mph --a constant noise like it needs to shift but the car shifts with no problems ---just this noise --any idea what it could be --the mechanic said it needed a transimission but it shifts so smooth no problems---but the noise must be coming from the tranny

Any help??

Check cv axles swrive from side to side see if the noise changes.go 45 put it in net and turd the key off see if the noise goes away

Try changing the transmission fluid, using a full-synthetic product. However, if you have not been changing the transmission fluid regularly, the clutch packs are likely shot and you're facing a rebuild.
