Default 4l60 issue

its not in my TA but my ZR2 Sonoma. Its the damndist thing. Driving around town it is fine even going up elevation and driving off road its ok. Its just when I get off the interstate at say 65+ or if I coast down a hill the trans seems to slip out of gear only to be put back in when you press on the gas pedal and accelarate or maintain a speed.

When it slips out the engine revs drop and the trannies wines like crazy. There is no clunking or anything either.

Sounds Like The Overrun Clutches Are Bad Or Something Wrong With The Overrun Circuit

You need to drop and disassemble your trans for that. So, if that is your problem a rebuild is in order. Ask some of our sponsors in the trans section for advice and pricing.

If your saying you let off the gas and it feels like it free wheels in OD then that may be normal. In over drive position the overun clutches are not applied and it will feel like a ten speed bike coasting , Not exactly but thats the idea the input sprag free wheels and the engine rpm will drop alot, When you give it gas the engine will have to catch up. Just like a ten speed
