The forward clutches are going bad is the most likely problem. To repair the trans should be rebuilt.

Testimonial: "That's what I was afraid of, a total rebuild. "
without having vehicle up on a four poster and putting my head underneath ?? as for the rattle ?? this could be pinking caused by low octane fuel ,95 unleaded is what it should have

You should have the computer scanned at a transmission shop or a dealership. If you get a code P1811, that is the 'max adapt long shift' code. That means that the Electronic Pressure Control solenoid may be going bad. Normal wear and tear on the clutch material can also cause this code. Basically, it means that the transaxle is taking longer than 0.65 seconds to shift, and the computer commands maximum line pressure to avoid burning out the clutches. I have had good success with installing a shift kit on several of these transaxles (4T65e) to remedy this problem with no further issues. Visit www.transgo.com and look for distributors in your area. The shift kit you need is the SK 4T65e shift kit. The kit comes with very good instructions. It is not a difficult job. If you can drop the pan and change your own fluid, you can install this kit.

David dont even waste your money on the transmission no slip fluid, its money you can put towards the new transmission. Once its slipping the stuff in the bottle is a waste of time. Learned this from past experiences, hope this helps. The reason the fluid is burnt is due to either worn friction disc or a fluid leak by the seals in the clutch pack causing the fluid to heat up and turn brown. Hope this helps.
