Change transmission fluid?

[Vincesrg03]

Got a question for the forum. I want to change the tranny fluid on my Yuk, but after reading alot of threads on here about the diffculty people have, Im sorta thinking i should pay a shop to do it. i serviced the Yuk last week, plugs, wires, diff fluid change(front and back), and oil change. I have done trannys before, but i wanna know if its better just to pay. It seems these trucks tranny's are kinda delicate(in terms of servicing). I know Jay is the tranny guru, so if he is out there maybe he can shed some light on this.Also what does everyone think about the myth, that if your vehicle is over 100k its not a good idea to do it? Local shop told me 120 for dropping pan, changing filter and fluid. What do you guys and gals think?

Honestly for the trouble its worth 120 to drop the pan, I personally would ask for synthetic and pay the extra cash too. One of the recent recommendations I read is to replace the boost valve when you service the tranny, as it can cause a loss of pressure as it wears...and that creats all sorts of issues like flares.

Somewhere on the board is that thread, search boost valve maintenance in the last months postings. Its like a $50 part.

I did a thread on another forum on how to flush and service the transmission yourself. Here is the link.

If you do not like to do mechanic work, then I suggest forking up the cash to have a shop do it. Otherwise, you can do it yourself. The hardest part was replacing the seal that the filter plugs up into. All together, it took me about 4 hours start to finish, but that was with me stopping numerous times, and cleaning the pan with carb cleaner before I put it back together. Another tip, use a little RTV sealant to get the gasket to stick to the pan. The gasket comes folded up in the box and does not want to stay laying on the pan. I put a little RTV sealeat on the pan and clamped the gasket down with come small clamps for about 30 minutes while I got a drink and a sandwich.
