Over 6k RPM hurts 200R4????

[injdinjn]

I was recently told that taking a 200R4 over 6000rpm is bad for it.
Is this true and if so what is the fix.
I normally run a 6600 chip and occasionally a 6800.
Thanks

I have mine set up to shift at 6000-6200 all by itself. Seems to be doing OK so far.

On a side note... what kind of cam are you using that pulls to 66-6800? Must be a monster.

Dumb question.
The ecm chip controls shift points?

No sir.. Valve body and governor combo control the shift points. I have an oldsmobile KC valve body and a BR governor to get it where it shifts @ 6k.

I had an 85 CR 2004R in my 75 Monza with a 327 and would shift that at 7200. Just had to make sure the direct return spring pack had all the springs and not the low rpm pack like the BRF's have. Never had a problem with it for 5 years and it went into an 81 Camaro behind a 10.00:1 454 for a few more years after I tore the car apart.

You need to run a very stiff pump slide spring for high rpm application. Its worth doing a few other mods to the 4th clutches to reduce some drag when going that high

High rpm can hurt the hi drum return spring assembly in the 2004r when the trans is in first gear.The drum turns backwards at almost 3 times engine speed .We are working on a correction.

Like a 2.4 planetary or something like that:biggrin: I hope
