I have Toyota lc II three door 1995 (L J - 72) with G 40 gear box (only four forward) original come with 3L (which I change with 2L engine non turbo), now I need to change with double top gear box (five forward) for fuel efficiency and for highway use. For said replacement I visit Saleem (Shershah), Chand (Shershah), Imran (Liquatabad Dhakhana), Imran bandhani (Graibabad), Auto gear (jail road) means visit all concern person in Karachi.
Conclusion & Result
Used kabli gearbox is around 50,000/- (and not available in Karachi) which I think G-52 or R150F both five forward.
Second and cheap option which they all insist is to upgrade your own gearbox to insert fifth gear in your own gearbox (means fifth kabli grari), which cost me around 7 to 12 thousand.
They all advise common that your gear has a space of fifth garari which is to be filled by fifth garari and some other gearbox items. And no need to change your gearbox and it is very common now to upgrade your gearbox with original kabli garari fittings.
Pl advise whether I replace whole gearbox or only upgrade my own gearbox with fifth garari.
