Hi guys im having some weird stuff happen with my rx300. Installed the new transmission after the old one didnt go in drive or reverse anymore.

Now im having a very rough 2000rpm idle. it comes and goes. steam is coming out of the radiator cap, New cap. getting code P1354 NOW!

i changed all the spark plugs.


i still have rough idle at 2000rpm , the steam is coming out of the cap and code p1354

also can someone please post a picture of the transmission cooling lines to the radiator

Did you try driving it? It sounds like you've either got the trans cooler in the radiator connected wrong, or you never got all the air out of the engine cooling system after reconnecting everything. Don't overheat the engine if you blow the head-gaskets that's another huge job.

okay changed the cooler lines now it's correct. The one that pours out from transmission I put it in the radiator and the other one is connect from radiator to the cooler.

Now im having yes sluggish gas and idle I have code p1354 😞
