second opinion] my 1995 lexus sc400 will go into reverse ...

my 1995 lexus sc400 with 93k miles i believe the transmission has gone out. i was driving it down the road at normal rpms. it all the sudden as i pressed on the gas it acted like it was in neutral. when i dropped the pan the fluid had a burning smell, small metal shavings, and completely black fluid. i changed the filter and fluid. still same issue. it shifts into reverse and neutral just fine. it revs up when trying to shift into drive but doesn’t catch.

alright thank you!

At the transmission solenoid connector check to see if there is a voltage signal to the Shift solenoid E or lock up. The Yellow wire is the positive side of the circuit. Check the resistance of the lock up solenoid. 7.5-8.5 ohms is normal. Check the transmission fluid to see if it looks burnt. Check to see if the fluid has been replaced. Check that the correct fluid has been used if the transmission fluid has been changed. If the solenoid resistance checks good and wiring checks good, replace the automatic transmission.
