4l80e no 1st gear

My 1997 C2500 GMC with a 5.7 and 4l80E transmission starts in 2nd and intermittently has overdrive. It shifts from 2nd to 3rd fine and never even tries to slip. There was no metallic "swirl" in the fluid, not burned, and no buildup of scum or paste in the pan or fuzzy stuff on the magnet.

Is it ok to start off in 2nd gear and manually shift up to 3rd and then overdrive?


You can put the shifter in 2, 3, or overdrive. It will still start in first and shift up to whatever gear you have selected. Try it, you wont damage anythingl

I have a 1990 GMC Suburban. The transmission is slipping. I still have reverse, 1st, and can manually shift into second. No 3rd or overdrive... it just slips. What should I look for?


is it a 4l80e electronic shift transmission....it may be an issue with the solenoid pack...you can take it to someone who has a scanner tool for the trans...if it is indeed a 4l80e

I have a 1993 f-250 u have to manually shift to 1st to take off shift to 2nd and still in 1st gear. Shift to overdrive and transmission will shift through 2nd 3rd 4th and then to overdrive with no problem....


When was last trans fluid & filter change? Should be done every 30k/3 years or sooner of you do any towing. I'd start there and get it flushed thoroughly.

I have an 80 series landcruiser with A442F transmission, built 1993. It will not select 1st gear or overdrive. It takes off in 2nd and shifts to 3rd normally, 1st gear can be selected manually and changes...


It seems like your "2nd start" button is turned on. The 80 series LC has a button next to the shifter which allows it to start in 2nd gear. If the button is not engaged then there could be a problem with the circuit, but that is not common

When my 2001 GMC Yukon tries to shift into 3rd gear or overdrive - it is like it goes into nutral. It never shifts to 3rd. 1st and 2nd gears does just fine.


this sounds like the pressure valve is going bad on third gear. cheap fix try Lucus transmission additive to increase the pressure.
To do it right go to a good transmission shop an have it serviced and flushed.

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.

Overdrive won't work

4L80E trans. Lost passing gear/overdrive suddenly


Bad transmission, that's not a good answer. Bring it to the shop [so we can guess around], not a good answer either.

A good mecahanic will respond with something about the solenoids.

I have repaired the 4L80E on my tow truck, I have to do that almost every year, the last time it ran perfectly but when I push the pedal to the metal, it shifted from 3rd gear to 2nd and stays on 2nd gear until I turn the ignition off and start again.

The transmission was totally rebuilded so the answer "Time to rebuilt the transmission" is not acceptable.

I took it back to the shop and the mechanic replaced both solenoids A and B, that was the only thing that hasnt been replaced before, it was just a guess but works

So, I am not a mechanic but my sugestion is to replace the two speed sensors and solenoids before you take the tranny out of the car and be carefull who are you taking the transmission to because guessing is not always the best course of action

The two speed sensors are easy to replace, the solenoids are inside of the valve body but you may be able to replace them without removing the transmission from the truck
