Update: So the box is dead.. or at least I only have one forward gear. I was a bit suspicious that I didn't have sixth gear as the revs were a little high on the highway.. So I have been in contact with the wrecker and they are hopefully finding me another one. I am wondering if the box knew it was faulty and it wasn't showing a light as a result.. I will report back after I install another gearbox...

Hey all, Wondering if anyone might know but I have an IS250 I bought with a stuffed gearbox. It initially had no led light on the dash to indicate what gear it was in, I assumed it was due to the gearbox problem. I have since replaced the box and it drives beautifully, love it but I still dont have a gear indicator light on the dash and the lcd display does not show any gear, if I shift over to sport it wont manually shift with the stick or paddles. Additionally I dont have cruise control, wether that is a separate or combined issue I dont know Otherwise I have cleared the fault codes I was having, reset the VSC memory ok. I havent been to Lexus to reset the transmission memory (My friends fancy scan tool cant read the trans ecu, I will go spend the money if I have to but hoping to find a fix myself if I can) It shifts thru the gears itself ok, so it's a minor issue really but would love to fix it (you know when that little niggly problem grates at you?) I have no fault codes, and have checked for continuity across the shifter switch in the console and on the gearbox mounted shift position switch ok, and currently at a loss as to what to try next unfortunately! Any advice is muchly appreciated 🙂 thanks kindly

The tach seems to move which suggests the crank sensor is ok. Are you getting spark? I did have a similar issue with a 250 I bought not working, it was a couple of connectors in the ecu compartment. It's hard to describe but there is a fly lead with all white wires that is usually capped off but it was swapped over with another set of leads that was plugged in to the loom (not directly into the ecu). Guessing it's for diagnostics or something, but stopped my car from starting, I will taker a photo when I get home (I cant find the random youtube video with the fix unfortunately) no idea why it was swapped over, but hope it works for you!
