problem with 6a12tt 4wd auto gearbox
i'm in the middle of converting my perdana v6 to 6a12tt.the mech told me that the 4wd gearbox cannot be locked to 2wd due to the gb is "newer" version.(he already sent to 2 mech for the 4wd to 2wd conversion,but they told him the gb will kong in no time if the conversion is done).this the number i wrote from the gb: W4A331UP 01 BC1983.i dunno if this info will be helpful.
FYI the model for the engine is e-e84a-srgf.my question:
1) can the gb be used without locking it to 2wd?i'm afraid to convert my car to 4wd (with rear axle..tank..etc) as i heard that conversion is totally illegal with jpj's regulation.
2) any suggestion on good/reliable mech that can do the 4wd to 2wd gb locking?
3) i notice that the speedometer that comes along with the halfcut have additional indicators i haven't seen before..i.e sport/tour mode(at the km/h meter)..front torque ratio(at the rpm meter)..and TCL-off,TCL,TRACE-OFF under temperature meter.what are those for?
thanks in advance for any reply.
