When did they go and how, also do you have pressure or a way to check the line pressure?
 
Sorry, Mark...

No Mark, well both Marks, he had some kinda hard part failure. I haven't a sure guess right yet and I am not very happy. This one is one of mine. I think the front ring gear or front sun gear failed. Planet splines may have stripped on output shaft. Something funny like that.
It isnt the drum or the front shafts. Planet, ring gear, or sun gear.
Just pisses me off the guy just wanted to race before end of year. I feel like shiiit but what can I really do? Well, once I figure it out I will post to reveal what broke.

Again, My apologies.

Hey Mark? Try manual low. See if car tries to move. Juust curious. In OD it doesnt move but try manual low. Let me know.....
 
Bruce
I have no low , rev is still good . I am not upset with you at all Bruce , anything can break at any time when you are racing , I preach that as I build motors for GN/T's in my area , I had several at the OK/Buick shootout this weekend , I am upset that I didnt help our team with my car as we lost only by a few races this year .

I will call you later today , dont sweat it WE WILL get to work I feel good about that , maybe uncover a weak link .

Mark
The trans broke about 30 ft of the launch , it wasnt to hard of a launch but it realy pulled hard about 10' out and something poped /snapped ,the mtr died and I coasted to a 36 second et :(
 
i'm upset. i've wanted to see marks car run all year. i honestly think mark's friends were more upset than him about it. dont sweat it bruce. we all know your a good guy and will serve mark well.

That's to bad, but trust me Bruce will make it right for ya, on that you can bet, and like you said I'd bet it's a weak link and not any of his parts. Good luck.
 
Same MO

The CZF trannie I just put together acts just like the one described here, rev but no foward gears. I even switched valve bodies but had the same MO.

I ran my CZF with all the PTS good stuff behind an engine on an engine stand with a yoke in the end of the trannie and had the following pressures and problems.

No TV Full TV
Park 120 275
Rev 120 275 Shaft spun like it should
OD 120 120 Shaft did not spin at all
Drive 120 120 ditto
Second 120 120 ditto
First 120 120 ditto

The pressures fluctuated a lot and a sound like a clicking hydralic lifter was very audible.

I took the valve body off, all the valves moved OK, there is no spring on the TV Modulator upshift valve.

The only odd thing during the rebuild was that the direct drum set in at 4 1/2 inches instead of 4 1/8 so I disassembled completely, found no problem and reassembled but the direct drum was still down more that usual and more than the ATSG book says. Talked to Bruce and he explained that a rollered setup would be down more than standard.

OK, so nothing is broken or missing what is wrong?

I think I'll call this one Christine.
 
hhrmmm

ok, first, no sun gear in front planet would do it. cut or not correct, or not there, rings on forward drum shaft would do it. ah,,, cracked forward piston would do it, manual valve is flipped over on s clip would do it. ah.. govenor o ring or govenor NOT THERE would do it. gov cover bolts loose would do it... govenor gear not there or stripped or broken would do it. Input shaft od sprag failure would do it too... thats all I can think of right off. :D
Marks deal is something broke...your deal is something was either left out or assembled wrong :( Either guy, both problems suck!

PS... Take it apart Clay. You will find it......I got faith in ya....;)
 
AEEEEEEEEEEEEE Again

Thanks for the "where to looks" Bruce.

I've tinkered with this trannie more than with my wife, according to previous post Bruce and I are one on this condition.

I'll take it apart again, when the new PTS front planets are available.

Just a word to the those who would try to rebuild your own 200 4R, if you have a job work some overtime and pay Bruce. It will involve less of your time. If you are doing this for "personal satisfaction" as I and others have "claimed" in previous posts--buy yourself a cat 'o nine tail on eBay--same satisfaction.

We are making the OD planet. NOT the front planet where I believe your problem is.

I like Doc Bruce better

My problem may not be in the OD planet but I've got to have some incentitive to take it apart, so I'll wait for PTS's next "I'll bet you cannot break this part" contribution to the 200 4R.

This is my third 200 4R rebuild, the other two are working fine thanks to this board, which I constantly monitor for problem solutions, and to Bruce specifically whom I have in my speed dial.

Built many SBC motors and know every engine turns out a little different than planned/designed and I believe the same about 200 4Rs. I'd bet that in spite of Doc Bruce's skill's, experience and knowledge every 200 4R he produces has slightly different rpm shift point, pressure reads and shift "feel".

The 200 4R is the most complicated mechanical device I have dealt with but I believe it combines the best weight, strength and efficiency of any GM trannie and will continue using it even in my 500 CID Caddy conversion. One day I'll scrape together enough dinero to have one done by Bruce. Until then, see y'all on the board and be sure to wave when you pass me when my car is on on the rollback. You sure as hell will not pass me when its running.

I would think the incentive would be you would want the car to move FORWARD. You said it would not move in a forward gear. What would be any more reason to disassemble than that? just kinda curious.....:)


AND......... I have the new planets now so get a rippin!! LOLOLOL
 
Spare 200 4Rs and phantom planets

I tested the 200 4R with the PTS input shaft, PTS forward drum and other goodies behind an engine on a stand, I have two 200 4R spares. It'll be installed either when I break the 200 4R now behind the Caddy engine or when I finish the hi-po Caddy engine I'm working getting together right now.

You don't have your OD billet planets yet. I looked on your website and they are not there. Anyway, I know you would post availablility on the board when they are actually available.

'Til then we wait.
 
I think he does have the new OD planets now just not the time to post them on the site.
 
Love the price!

All right $0.00! Do I have to pay shipping or is that included in the purchase price?
 
You'll take 5 at that price huh?
LOL
Like Mark said, time has been a great enemy of mine as of late.

I will have it all up next week after Vegas. My car blew up Friday night, ( wasnt real fond of 24 psi & turbo blew) and I am busy trying to get back together before we leave thursday.


But I do have them in my possession.....:D
