I finally made the decision to change my 'faulty' tranny (Mitsubishi's tranny code F4A222NPF) last weekend. Fearful that prolonged usage will cause the autobox to jam whilst driving at high speeds on the highway, I then decide to seriously consider a tranny change for safety on the road for others, including myself.

After 2 weeks, from a stand still, my car started on 2nd/3rd gear and so had not much momentum to move the car. To use the car as smooth as possible, I had to frequently switch off the OVERDRIVE button to minimise gear shifts and hold on to lower gears longer. Early morning engine starts will have a very loud pitch equivalent to 'slicing' of the plates and/or straining of the autobox. My auto tranny experienced heavy judder and shocks (from gear shifting) after an outing out of town in hilly terrain. If you have to undertake repairs on your own Proton Perdana 2.0 then it will always be recommended to possess a Workshop Manual to use as a reference if you want to know tips to strip off a certain component for example Gearbox and fit it again the right. Recently I decided to change the gearbox to manual. Is it true the V6 has got more gearbox problems, but the SEi model gearbox no problem.
