Question about 1995 Lexus LS 400
IT RUNS GOOD BUT WONT MOVE ,IT ENGAGE BUT WONT MOVE ,SPEEDOMETER SHOWS MILES PER HOUR BUT WONT MOVE.WHATS WRONG WITH THE TRANSMISSION????
I agree somewhat with Pfeiffer, and it may be overfilled, or under filled. The problem really lies in the gunk being loosened up and then starts moving through the filter and transmission if you have too much fluid well its about the same as having too little. The gunk gets into the tiny little orifices and wreaks havoc. The other possibility look at the shifting solenoids. LS400 is a bullet proof transmission and very picky.

Try adding a bottle of Lucas Oil Transmission Stabilizer...add when motor is warm...tranny filter is most likely clogged and dirty...this additive works on most...

Yes the ECM can indeed cause these issues, if they (the shop who diagnosed it) replace it and it does no cure the problem then they just bought you a new ECM as they are not returnable.

The check engine light comes on mostly when you have bad gas tank cup,or you don't tight enough the gasoline.Go to any auto-zone and request the obd scanner,at no charge just leave your driver license or credit card,connect the scanner follow the instructions.They will check up and the check engine light will come off in the next 3 to 5 days.
Thank you !!

Since both gauges died at the same time, I would suspect either a connector issue with the dash cluster, or a signal issue from the computer. The RPM signal originates at the ignition and the speedo signal at the VSS. The likelyhood of those both dying at the same time is very slim. An easy way to check is to attach a scan tool and check in the computer for an RPM signal (running) and a VSS signal while driving.
Hope this was helpful!
