Buddy why do you want to go for TR with 3-4 months time remaining on CPL ? You will feel really bad if something goes wrong considering how good DGCA are with their regulations & interpretation of rules.
I know there was a member with Zukerberg nick who did TR on 320 before 3-4 months of expiry and got his CPL renewed.Search his thread.
Spend 50-70K Rs on Checks if you have 172 on CPL and then start TR with new renewed CPL.Peace of mind if i was you.
Fly 10 hours as PIC in 6 months - CPL renewed on that basis.
Fly the checks - CPL renewed.
Do TR but depends on DGCA.
