Question about Lexus Cars & Trucks

Open Question

I have a 2003 m45, It has manual mode but has a safety feature that auto shifts even when in manual mode. I need a way to keep it in 2nd or 3rd even if rev limiter is hit.

I want it like my lexus in manual mode that holds gears even though both are auto. Needing it to stay in 2nd or 3rd. I do have the tcu pic if needed

Your trans is slipping, u are going to need to have it checked out at a trans shop, they will test drive it in most cases for free and report what they think is wrong or recommend more diagnostic work if they are unsure..

Shift lock


It could possibly be a bad electrical connection or poor connection with the transmission. Did the mechanic get any error codes?

Transmision starts out in 1st shifts to 2nd then third but will not shift into overdrive , but once it reaches 3rd gear ,it stays there when you come to a stop . after that it will only shift manually...


Sounds like your transmission is in limp mode. This is a fault mode in which the transmission either loses electrical power or the PCM deactivates all of the electronics. The transmission will default to max line pressure. The driver will have Reverse and 3rd, with manual 2nd available by putting the gearshift in 2 or 1 (doesn't matter). 1st, 4th, and TCC lockup will not be available. It will not hurt the car to drive it like this for short periods, but use manual 2nd to get the car moving, and be aware that the trans will generate more heat than normal while operating in limp-home mode due to increased torque converter slippage during 2nd gear starts and no lockup in 3rd gear.

The other from what you described, trans shifts 2nd to 3rd by itself in D or OD and locks the converter : ShiftA solenoid failed. Easy fix in the pan. Or a wiring problem from PCM to trans.. or PCM.

Thank you for using fixya and have your Safari scanned for the DTC codes that would indicate what issues your transmission is having to put you in to limp mode.

I have a 2003 camry,4 cyl engine auto trans,143000 miles on it, just replaced the trans with used unit with 20,000 mile on it, car dose the same thing, when shifting from 2nd to 3rd it holds the shift high...


Usually burnt and discolored ATF mean pump or torque converter not doing there job or bands and clutches are worn. Shift solinoid or a pressure problem is the problem with 2nd and 3rd gear, Take it to a transmission shop and have them look it over but like I said earlierdiscolored ATF could mean a rebuild.

1996 gmc jimmy won`t shift from 1st to 2nd


IF the abs dash light is on and if the speedometer is sluggish or not working at all, it is probably a bad speed sensor on the transmission. and easy fix under $40 for the part. Mine was stuck in second gear for a while then worked then it stuck in first gear and i had the CHECK ENGINE light on.

4L 60E - 2001 k1500 will not shift into 3-4. Oil is not burn't and stifts great into1-2


  • No 3rd or 4th gear: “3-4” clutches are worn out. R&R. The car is safe to drive (in 2) until you can get it fixed.
  • Trans shifts into gear harshly, car feels sluggish off the line, No 1st, 4th or TCC lockup available, Manual 2nd, 3rd and Reverse are only available gears, CEL is on: Transmission is either in limp-home mode or has lost electrical power. If there are lots of error codes in the PCM, check the under hood fuse that powers the transmission, and if it pops again, look for a short in that circuit like an O2 sensor harness touching exhaust. Otherwise, check PCM codes for a particular fault in the transmission causing the PCM to put it in limp-home mode.
  • No 1st or 4th available; trans shifts 2nd to 3rd by itself in D or OD and locks the converter : Shift A solenoid failed. Easy fix in the pan. Or a wiring problem from PCM to trans.. or PCM.
Check to see if your transmission is in the limp mode, which would only give you 2nd, 3rd and reverse gears. No 1st or 4th gear.
