answer to any 4l60e trouble

[Zbarbwire152]

Couldnt find my problem in here. Ive had a problem recently where if i give it more gas to where the pedal is on the floor the RPMs go up and it makes a ton of noise but never shifts up nor increases speed.

Sounds like slipping to me. Check the basics like fluid but I'd be planning on a rebuild.

Or you broke a hard part inside the trans. Slipping usually doesn't make any noise, but if your getting some racket then something probably broke.

sounds almost like your torque converter..............

I got 97 4x4 with a 4l60e,

I'll start drivin and it wont shift into 2nd till 4k then once its in second it wont shift any higher, it'll just go to the rpm limit. From 2nd gear i manually shift into 3rd and it just revs up. i bought it a couple months ago to do a restoration (in progress) and he said drivetrain was great , ya well i got screwed over there idk why i didnt test drive it for some stupid reason. But im guess a R&R

I bought a '95 Chevy 4X4 for a restoration project, previous owner randomly lost reverse without noise or warning. The rest of the gears worked and the truck shifted fine, I actually drove it to work for awhile while my '93 was in the shop. Checked the fluid right after I bought it and it was blackish brown and low. Added more new fluid to top it up and still nothing. If I'm moving slowly forward and shift into reverse the truck shakes and shudders and comes to a stop but then acts like it's in neutral. Pulled the pan and put in new filter but waiting on tensioner (truck doubles as parts truck for the '93) to see if I can reclaim reverse. I lost reverse in the '93 for a few days but managed to get it back by adding fluid and revving it up slowly, then it slammed into gear and I started flying backwards Do you think I'm wasting my time? Thanks

So my trans is slipping once I get above 4000 rpm in first or second at WOT. would my best bet is to change the oil and filter and tps and then go from there?

hELP ANYONE.
have a 95 C2500. 160000 miles, 5.7 liter engine. auto 4l60e I believe the 3-4 clutch paks are bad. I have I have first and second but third slips and it can't shift to fourth.

I pulled the pan and it was clean, fluid clean.

The numbers on the case are 95 42894 and 2420222G 4l60e
The valve body numbers are 94 286 5A 293 Lester 1 868 4212.
If that is a non compatible valve body, that could be the cause of the failure.

I can get a bone yard M30 out of a 95 van with a 5.7 engine. Will that swap or not?? A local tranny shop told me 95-97 are totally interchangeable. I've read that 95 are stand alone and not interchangeable with any other year with out using a 95 valvle body.

The speedometer is not consistent. Would that be the VSS on the tailshaft?
The windshield wipers are only getting 5 volts--I hread an ignition switch could be the problem????I dont know.

Is the M30 a 4l60e made in Mexico. The tranny shop told me that.

Any help will be greatly appreciated.

I made an error on the last post on my CASE NUMBER 95 4294 2420222 g

I read that M30 is a GM code for 4 speed auto.

Can anyone direct me to a website to decode my transmission numbers.
Also compatability, like will a 95 van work in a 95 truck.??
