Dear pakwheelers,

I have got a 1991 landcruiser prado lj78 with auto transmission. For over a week now its 4th gear is not engaging. Got the whole wiring checked and electeician told me to replace its ecu (engine control) he swapped it with another and it worked fine.

PLEASE suggest if my ecu can be repaired because I dont want to spend 10k for the ecu rather I would go for a manual transmission spending few extra bucks. Please suggest any ecu repair shop or mechanic in lahore.
Regards
