this made mine last two months. then again it had done 140000kms since it's last hg. as trev said, it's a factory problem that can easily be fixed and from what i know only happened on the 7MGE's not the 7MGTE's. very under rated engines the 7M's. the guy who built KE355 (the green wagon with the whopping great supercharged v8 in it) had a cressida with a 450hp at the wheels 7mgte. he said it would step sideways at 130 when the boost cut in in 3rd. won't need this much power in your 55 but the ability is there.
