Another note if I may add: a parts driver for Mopar who comes to our shop just had his tranny rebuilt on his Bonnie....the guy who did it says he sees the main gears destroy themselves all the time...theyre made of a cast iron instead of a hardened steel....they wont stand up to much abuse ,ie: brake torque, neutral drops, wheel spinning,fast starts...he will only install hardened steel gears on his rebuilds....

From my experience with 4000 bonnevilles here, I can say I've RARELY seen a gear go. Mine was an exception, as I did lose PART of my second gear. About a third of the teeth.

And the gears in the 4T60E-HD at least are hardened steel, not cast. I can't speak for the 4T60 or the 4T65 non-HD'* though.

Being a constant velocity shaft....I really don't think that could have caused this......Seeing in the pics how his angles and how much the cars body really moves vs possible suspension movment.....should all be normal. also the only real pheasable way I can think of to push a CV shaft passed it'* flexing limitaions is if the wheels could turn WAY far out, but even then you'll hash a boot before that happens. I also don't think there'* any way he could articulate it to surpass his vertical limitations.

I had the trans on my 1995 SSEi replaced just last month. The total cost was $1898.00 US, including converter and complete overhaul. The stove pipe was split in two pieces and was replced. The valve body and trans has all the upgrades from Sonnax and all the clutches and related components were upgraded.

I'm assuming you're from WA? Who did the work for you?

SeaTac Transmission in the Sea Tac/DesMoines, Washington area. Highly recommended; they do lots of work for a friend of mine that owns a dealership and they also had done work for me in the past. They are also the largest warehouse parts distributors for transmission parts in the Northwest.

There is also another shop in North Seattle that does an awesome job and very knowleadgeable on our transmissions. I will post their name as soon as I find the card; did not take the car to them due to their heavy schedule.
