Gearbox Leak IS200

[NathanG257]

Hi, I am struggling to find help on this but basically 

I have an is200 recently had new clutch and gearbox fitted and new slave cylinder but every few days I have to keep refilling the gearbox and after a drive down the motorway or dual carriageway the a strong smell of burning transmission fluid and a bit of smoke from back of engine or coming for under the side of the car and then after few more days my gearbox goes noisy when first starting io and driving but then quiets Down a bit when warmed up but I cant see any leaks? I'd much appreciate any ideas or fixes. Thanks

Sorry to hear that, but first question, did you checked all the seals of the tranny before installing it? Is this a new tranny? How many miles are on it if isn't new? And have you checked underneath of it to see where is coming from, if it from the bell housing or the outup shaft?

Im not a Lexus expert nor even a toyota, however I'm a VW/Audi technician so i do have plenty of knowledge and experience but first time Lexus owner with the same car so I'm learning as i go, already dismantled and reassembled the top en of my car several times since i bought it, i also did a pre cat delete my self and i definitely recommend it, it feel and sounds like a hole different car.
