SOURCE: 91 gmc shifts in and out of overdive

I had an 89 Suburban that started doing the same thing. Change the fluid/filter and add a quart of Lucas Transmission Fix. See how that does. Ultimately, you are going to have to rebuild or replace the transmission as the problem will only get worse in the end. Mine finally went down completely and cost me about $2700 to rebuild.

SOURCE: Hi i have a 1995 gmc jimmy. I had some tranny

Being that after you changed the fluid and filter out and the shifting got easier but you lost a gear that tells me that something is coming apart in your tranny. Transmission fluid is highly detergent so if you put new fluid in a allready failling tranny most of the time the new fluid will wipe the tranny out the rest of the way. If that truck still has the 700R4 or 4L60 tranny you can try turning the car off, with the tranny in park, stomp on the accelerator peddle several times and hopefully that will free up a possible sticking throttle pressure valve. You can also try replacing the lock-up solinoid inside of the pan but that most likely isn't the issue.

Sounds like the trans. is shot, try a quick service (Fluid and screen) if that doesnt work try a used trans.

SOURCE: can a electical problem cause the tranny not to

Hi, the trans in this year, has a 4 wire connector that is for overdrive only, the loss of gears is probably a mechanical issue internal to the trans, and an overhaul is probably in order. I would take it to a local trans shop, as diag is usually free. This will give you a better Idea. Good luck...

The Transmission shifts very hard after the first shift. Check engine light is on as well as the Green overdrive light blinks off and on. Speed sensor was cleaned and even replaced.


Your on the right track. Have you scanned the PCM, what codes did you get? If not and you changed the vehicle speed sensor,(VSS) did you check the (OSS) output shaft speed sensor, it will cause torque converter lock up and hard shifting and that pesky OD light flashing. I have also found that clutch packs inside auto tranny's dry out. Ford and some aftermarket companies sell a fluid that will recondition the clutch packs.

2000 gmc jimmy will not go into overdrive


There are a number of things that could cause this issue.

Now this is going to sound kind of "out there" but, does the engine temperature actually come up to around 195°, more or less?

The reason i ask that is IF the engine isn't up to proper temperature the computer will NOT allow the transmission to shift into overdrive.

Hope this helps.

42re tranny in my 93 jgc seems to be stuck in low gear. 1st & 2nd seem to be the same and won't shift automatically at all. Will not shift into overdrive. Changed throttle position sensor, new tranny


if its not shifting make sure fluids are full (I'm sure you did) im just saying is your speed sensor on trany pluged in , and your throttle return cable from trany to fuel return hooked up

Can a bad o2 sensor cause the transmission to shift incorrectly


No. your problem most likely lies with your shift solenoid in the tranny-pan.

1999 chevy lumina doesn't shift into overdrive, why?


If it won't go into overdrive a speed sensor within the transmission may not be sending the shift signal to the transmission. Check fluid levels to make sure that's not causing the problem. Also, check that the fluid is red color and clean.

Transmission probably needs to be serviced at a reputable shop if you want this problem fixed.

Your transmission fluid contain water,thats why the colour of the fluid changed to pink.And of such the clutch is slipping causing the engine to reve up before shifting - Check transmission cooler.
