Code po440,small leak in evap,.. And..
GM Gent's I have a few questions about my 02' 2.7 boxster,..1. that 440 code says small leak in the Evap system, can I assume that that's a fuel system leak of some sort.
2. lately after a gear change and clutch fully released I get a little hesitation,could that be a result of probably needing new chain guide pad's my last Deviation number's are 3.75 and 8.75,..and I do have that nasty startup noise,.very briefly but very noticeable.
Now for the curious question's,.is it impossible to install the 6sp trans from a 2000' Box S into my 2.7,..and can I also use the Mo30 suspension system from that same car,.?? I have the car with a blown engine,..or is it better to install another engine and put the car back on the road,.?? Thank's Very much for any info that you would share..Frank

No, P0440 is an EVAP system leak:
-EVAP cannister purge valve faulty
-Blocked purge air line
-Leaking EVAP system line leading to the air intake system
-Leaking o-ring seal on gas cap

Yes you can install a six speed trans in the base car, but along with the trans, you will need the six speed axles, which are different, as are the suspension uprights, hubs, and even the emergency brakes.

Believe it or not, fifth gear in the five speed is more overdriven (0.789) than the sixth gear in the six speed (0.84), plus the six speed adds a lot of weight as well.
