So blackbear performance tuned 57000 mile stock origional fluid 4l60e behind a 5.3 driving 35's on stock 3.73's and g80.


I went to go in reverse yesterday like normal from park and after it rolled i gave it a little throttle since it was an incline and all the sudden BANG! I about **** a brick and let off the throttle immediately, put it in mark, looked underneath but didnt see any leaks or problems. Reversed again but no bang this time.

So I get home after my second job, no problems when i left work backing up, but when i put any throttle to it backing up at home same thing.

Now today at work I went to back up and the bang was there again but it sounded like a fan as well and no drive power.

I am really worried because there is no way I can afford a 2-3 grand bill for a rebuilt one and this is my only means of transportation. Its hard to diagnose something on the internet, but any ideas are helpful. My dad is coming up to take a look at it (30 years GM master tech) so I figure he would be able to find out.

Anyone know where I can get a mildly built 60e by monday? lol.

best bet is just to get another one and throw it in there. junkyard maybe?

i dont know of any yards around, probably wouldnt trust them. I knew I shoulda never put off the 4.88 install, too much stress to the trans in my opinion. I guess ill find out when my dad gets here. I hope its a ujoint or something simple so I can go to new era open house tomorrow.

Your trans is done.

If yours is an 07 up you need a 4L70E which is similar but has a front speed sensor on the input shaft.

fortplainman

only person i know of that is close to me (3hrs) is performabuilt and i saw on the website that they dont have the core for 07-up 4l60e they need mine to do the build.

might want to check the g80 as well. so you were able to drive to work after the first bang, then after second back trying to leave work no longer drives?

you also need to regear lol

ive driven it the past two days about 30 miles total to/from work no problems shifted fine in any forward gears, just happened 3 out of 6 times in reverse in that timeframe. the last bang moving in the garage i have not tried moving it since. if anything i would rather have it be the g80 i have a truetrac and 4.88's sitting in my basement at home from ron for the almost 3 years, just hasnt worked out to install them either no money, not home, or couldnt get a vehicle to use since this is my DD.

Start calling junk yards and put a used one in there or get a reman unit from the dealer.

fortplainman

just called the dealer its almost as much as a built 60e. ill look up junkyards around here, see if i can get one cheap or maybe invest in looking up an 80e gmt900 4x4 swap since i wouldnt mind down the road a year or so get a little more power.
