Auto gearbox issue after head gasket failure, Auto gearbox issue after head gasket failure Options

Hi there everyone - I just need some collective wisdom from all you wise ones out there.
I have had a traumatic month or so with my auto gen6 JDM ST202 convertible. After carrying out several repairs on the roof etc I was looking forward to the warmer weather when the head gasket went, along with a couple of oil seals. A bit of a mess.

So, this being beyond me, I put it into my faithful garage who I've been going to for years. It was returned to me a couple of days ago, all seemed fine and I seemed to have gained a bit of torque from before!

However, now I have it back, it's driving nice APART FROM the other day it suddenly slipped into neutral at the lights, the rev counter suddenly shot up as it lost the resistance of holding the car on the brake.. I've also noticed an occasional slight delay in picking up from a standing start. 98% of the time it's fine. I can't see anything obvious, there are no leaks including from the auto transmission fluid.

Before I go back to chat to the garage (who I get on well with) I want to just establish whether anything in the Head Gasket Work might affect the gearbox in any way. Can't imagine it myself but thought it was worth a heads-up here.

You can drain and fill it yourself at home if you have a set of ramps or even with the tire change jack. Drain the fluid into a pan and pour it all into a gallon jug then pout clean new fluid into another gallon jug and put them side by side to match the level. Put back in what you drained and your level will be the same as before. Drive the car and do another drain and fill, then in a week another, you'll have nearly all the fluid changed by that time. Then after do it once a year and you'll always have essentially new fluid.
