Transmission engages but after 30 seconds drops, any gear
Hi all,
I have been looking around for similir issues, but I have not been able to find someone with a similiar situation happening. I have a 1998 Chevy Blazer and when cold, transmission engages and all gears work correctly, but after like 30 seconds, the engine revs a little and then no gears, The car does not move either back or forward. Has anyone experienced this before? Is this a sign that the transmission died or could be something electrical or maybe something that has to be with the filter? I checked the oil and is darker than it should, also checked if there is pressure on the transmission pump and there is.
Any help is highly appreciated.

If the symptoms came on all at once, then I would think the fault is with something central like lack of fluid due to a plugged filter.
Transman304, could there be a problem with the torque converter??
A filter change can be done at home so it might be worth trying. Also you'd get a feel for what could be going on in the transmission by looking at the contents of the pan. Word of warning, it is a messy job.

Absolutely could be a torque converter issue. Typically when failing the converter will work until it gets hot, more than 30 sec. Not worth the cost of fluid and filter and time. Something had to fail inside the transmission to produce the debris. About only option is rebuild or replace with used. Still curious how they tested the pressure as stated in the original post.

So, after talking to several shops and a mechanic that came home as I was not able to move the car, everything seemed like I needed a rebuilt or new trans. I was skeptical about why the transmission engaged for a few seconds then dropped, so I tested the pressure (super messy job as I mistakenly cover the wrong output of oil in the radiator) and there was pressure.
Got the filter,gasket and new trans oil, opened the pan, replaced filter and now is running like new, shifting is super smooth and got it to work!!
So it was a clogged filter indeed. Worth the try! Thanks a lot!

Awesome!
Glad to see that it worked. I have the EXACT same problem with my Grand Caravan Dodge 2014. Every mechanic said I needed a transmission. And said a flush or filter change was a waste of money. I too felt skeptical because the tranny would engage and drop after about 30 seconds too. So I ordered the filter and the oil and some Lucas stuff. Then I came across your post. I am very excited to see that this worked for you. If this works for me as well, I will follow up with you guys with a full report.
