Questions about 200 4r
guys, im getting ready to buy a 2004r, ive read all the articles i can find, but there are still a few questions i have left...
is it possible for me to rebuild it myself? i am very mechanically inclined, i think i could do it, but i dont really know where to start.
what stall converter comes with them from the factory? this is coming out of an 88 monte carlo.
any recommendations about parts? what about shift kits? which parts should i build it with and should or should i not install a shift kit.
im going to have about 420hp in front of this tranny, but i am planning on a little more later on.
also, any advice you can add would be greatly appreciated.
THANKS!! :yesnod:

Re: Questions about 200 4r (SharkBit)
You can do it.
I've always done my own work, but the TH400 in the vette was my first
tranny rebuild. I used a B+M Transkit. It comes with all the parts you need -
except for the bronze bushings. It also comes with optional parts for shift
improving. The directions with the Transkit were GREAT. I also bought the
Haynes tranny rebuilt manual, which covers TH400,700R4,200 4R, and TH350.
The manual has lots of pictures - which help a lot.
I can't help you with the converter choice.

Re: Questions about 200 4r (redwingvette)
I've done several auto trans over the years - diff types - I'm just a
home DIY old hot rodder. You need a large flat clean place, like a
sheet of plywood. When you take things apart, lay them out in sequence.
Helps going back in. What you really need is a good rebuild video - don't
bother with an ATSG manual - POC! Go to Jegs, Summit, or check these links
out. Oh, you need heavier duty parts - on one of these links there is something
like "extreme duty" or something - those are the heavy duty parts you need.
(I'm researching doing the very same thing for my 81 with a near-400hp 350
with a little over 400 torque). Depending on your rpm range and gears, and
what you'll be using it for, either the 2200 or 2500 rpm lockup. If you've got
a lumpy cam with soft low range throttle response, go the 2500. If you've got more of a mid-range motor with decent low end, a 2200 isn't bad for every day, esp if you've got 3:54 or deeper. By all means, read the info on these websites. Good luck! Oh, for sure use synthetic fluid and get a good cooler like a plate type (they're smaller & more efficient) B&M. Even a good trans temp gauge is a good thing - keep your tranny temp down and it'll live a heck of a lot longer.

Re: Questions about 200 4r (SharkBit)
guys, i seen the tranny that i am going to buy yesterday, but i have one question....when we took the engine/tranny out of the car, the tailshaft is wobbly, like, from one side of housing to the other...is this repairable? as in a bad bearing or something? or should i just move on to another tranny? this car ran fine, the tranny has about 150,000 miles on it, but i have to rebuild it anyway, but it was in a wreck, im wondering if the wreck could have broken the tailshaft, because it broke the rear axle off the car at the housing
thanks
thanks

Re: Questions about 200 4r (SharkBit)
There is a bushing in the tailshaft that is wore out. Once it is replaced the play will be at a min. I would upgrade the $%^$#% out of it, if you truly have 420 hp and buy the torque convertor you can afford.
IM me if you want to buy a 4 speed shifter, console plate, auto overhaul manual, and dip stick. All were only used a month. The shifter comes with a chrome ****.

Re: Questions about 200 4r (SharkBit)
I installed the 200-4r last year and love it.I used aTCI rebuild kit from Summit which has every part from clutches to shift kit.I also used the TV recalibration kit from BTO,GN servo piston and GN convertor[2200 rpm].The trans is an easy rebuild but you will need to buy or make[as I did]a compressor for the front spring.Also upgrade to a 10 vane pump rotor.These parts along with the servo and TC can be purchased from a local transmission parts house[not repair shop].I have this trans behind a strong 383 along with 3.73 gearing.Tire smokeing low end and super highway cruising.

Re: Questions about 200 4r (J75)
have you had any trouble with it? also, the spring compressor, do you still have it? would you be willing to loan it while i rebuild the transmission? or at least show me how you made it? thanks!
