Sir i guess its too late now as you said earlier that the transmission pump is not working so gear sometimes engages or dog ears in trans pump that may be broken as u said earlier, but karr karrr karrr type of sound does comes from trans in parking gear when i rev up and also after gear engages, it is the first time this kind of problem appeared so i ve parked it since then 3 weeks gone.
so now i have several options
1. make it manual (costs are bit higher than option 2)
2. change with auto trans of any other car which can fit this engine (i m not certain that which car's trans would fit on this engine any idea? ) (this option would cost less if the gear is in abundance in scrap market like vitz,duet,660cc
3. replace the whole engine with vitz 1SZ ( now thats a big investment of 50k and i would b doing this under loans )
sir what would you recommend on this im confused.
