95 ls400 tranny problems; help me please!!!!!!
recently i took my car to a small shop for a complete tune-up. well he changed the transmission fluid and didn't put toyota iv fluid back in the tranny. well i could drive the car until it would heat to normal and then the trac light would blink and the car doesn't move. i could turn the motor off for a few minutes and then proceed to drive again until it heats to normal.
1. i did a regular drain and the fluid was already black.
2. i put toyota iv back in and disconnected the battery to reset the ecu.
3. now the car will not go in any gear except park.
i know i need to flush the tranny and when i did the partial drain i noticed metal shavings. thats not good huh. i am lost and frustrated. and please don't tell me its time for a new tranny. this will be my second one. and its not cheap. somebody please help me.

I hate to say it, but it seems as though this car has been neglected in the past at some point. If you have gone through 2 transmissions, you may be experiencing heat problems. May I suggest that you check your radiator oil cooler in the bottom, or perhaps install an auxilliary cooler?
You say you see metal shavings, and that is definitely not good. Perhaps shavings from your old transmission has been allowed to come in and contaminate your newer transmission. Many people forget to check and service the entire radiator and cooling system while replacing a transmission....remember, SOMETHING caused the transmission to fail, and normal wear may not have been the reason.
I also believe that you can move up to something better than Toyota Type T-IV fluid. I may get a few flames for this, but Mobil 1 and AMSOIL make excellent fluids for both your transmission AND your power steering system. Put synthetic in both of these systems, and you will go a long way towards eliminating big repair bills in the future.
In your case, I would first drain the pan, remove and replace the metal screen, then refill the transmission. Idle the engine, run the car through teh gears without driving it then shut it off.
Then remove the rubber transmission line going to the radiator from the transmission and put in a large drain pan. Start the engine and while watching the fluid come out, keep pouring new fluid into the transmission. This will help drain the torque converter since there is no drain plug on the converter like Ford cars.
Once the fluid runs clean into the pan, you can assume that the majority of the fluid is clean. After this if the car still doesn't move, then the transmission is probably shot. This sounds like a lot , but it is still cheaper than a new transmission.
GOOD LUCK!

i am in a similar bind. i own a 98 ls400 and recently did a half *** drain n fill during an oil change. it ran fine for a couple of weeks. my father came from out of town and borrowed the car for a few days. he was waiting on a red light when the car ceased to move and the check engine light came on. scan tool read 3 codes: p0715, p0500, and p0750. i'm hoping that the new fluid freed up some gunk and is now stuck somewhere in the valve body. if not, i'm gonna have to replace a pricey solenoid. i'm gonna do a complete flush and replace the filter. i also have to diagnose the speed sensor connections and the sensor itself. whatever the outcome i shall post it on here.
