Truck is in overdrive, make a turn doing about 25-30 mph, stomp on it and the tranny is just above dropping down to first gear, feels like it’s slipping tell I get to about 8psi (stock gauge) then grabs and pulls right rear down. Is this normal?

I asked the dealers tranny guy about it, he said a chip would probably take care of the issue?

Is it line pressure?

Stock 01 L with catback.

Thanks…

 

Thats great, so now the dealers people say chip your truck

 

Yep... He told me to remove it for service...
