Here's the article I was talking about

Tuning

Governor
Replace the governor if its only shifting at 3600 RPM. Get one for a Monte Carlo SS or 442 which will shift the highest of any 200-4R governor (5000 RPM).

Here is the scoop on 200-4R governors:
The governor in a 200-4R controls wide open throttle (WOT) shift points. The governor consists of (2) weights and (2) springs. The lighter (smaller) the weights, the higher the shift points.

All non performance trans received governors that were designed to shift at 3000 rpms WOT. Monte SS (CZF) trans shifted at 4800 rpms WOT as did the 442's. The 84-85 Turbo Regals shifted at 4800 rpms WOT, the 86's shifted at 5200 WOT, and the 87's shifted at 5000 rpms WOT. You can buy these directly from GM at about $60 garage cost.

Some common governor problems: Occasionally when the trans shifts from 3-4 at WOT, the springs in the governor like to fly out. This will cause a no-shift at WOT from any gear. The solution is to drop the pan, take out the governor and put the springs and check ***** back in it. It should be noted that the 86 & 87 TR trans only have one spring (thus higher WOT shift points).

It should also be noted that the trans line pressure also influences the WOT shift points. It you use Art Carr's high pressure valve and spring, the RPM's quoted above might increase. I ran into a problem where my car would not shift at WOT. I checked the springs in the governor as mentioned above, but that wasn't the problem. I had the Monte SS governor in the trans as well as Art Carrs high pressure spring and valve. I wanted my 403 to shift at 5000, but the RPMS kept creaping pass that at WOT. I felt it eventually would shift at 6000 rpms or so, but at the expense of my 403 staying in one piece. So I put the original Monte SS valve and spring back in the trans and lowered the line pressure considerably and that solved the no shift at WOT problem. Now the car shifts a 5000 rpms very consistently.

 

got the spring back in...

Now I wonder if there's supposed to be another spring for the other side

 

now I'll have to find the other spring...

 

According to this site that's the way it goes with only 1 spring.

Might want to wait and call Art Carr to make sure.

 

gonna call him tomorrow.. I'll check if I can use another spring that I could get at the speed shop locally...

Damn - I'm glad that it seems that my issues were only caused by a popped out spring

Can't wait to put the tranny back together and see if my issues are gone...

 

Fixing one spring in your transmission is NOT going to cure all your Issues!!!!
After all you've done I'm expecting a # in the mid 10's or better!!!
May the Corvette Gods Smile at you you're next trip to the track!!!!

 

I still have a lot of tuning to do... but the major issue right now was the governor...

Ran 11.05 with the tranny working and the hardtop flying off..

Now the weather will be 15 degrees warmer, so I can't expect to get close to that time... I still hope to be in the low 11's for now.. Might also go dyno tuning to get the maximum out of the current setup.. Planning on changing the intake in the next couple of months.. The Super Victor CNC should give me at least .2 at the track... I could get close to 10's with the Super Victor CNC even in summer and mid 10's in winter... That's the only performance upgrade that I can think of right now.... Maybe some more work on the carb could give me better performance too.. We will see...

I also have not used the transbrake yet.. The transbrake alone should give me .2 seconds (at least). Using the transbrake and the Super Victor CNC should be almost a guarantee for mid 10's in winter... We will see...

 

EDDIE, I know it's frustrating, but that exchange was the funniest I've seen in a ling time. You two ever think about doing a stand up routine?

Later.....

 

I agree...you guys sounded like Abbot and Costello. Who's on first? I dunno...third base. ROFL!!!

BTW...even after you put the spring crap back together, what's to stop the whole thing from happening again????

It's the way that I'm doing the burnout that caused it to pop out. CPT gave me some pointers on how to prevent the spring from popping out..

 

ACK! You GOTTA be kidding!?!?!?!?!?!
C'mon Olivier....get rid of that POS and get a turbo 400. Doing burnouts the wrong way...good grief. Next it'll be wearing the wrong color sneakers while driving the car.

There's no way I'd go with a horsepower eating TH400!
Maybe for my next setup.. Planning on a blown 1000+ HP setup in 2 years..
If I'd have that kinda HP, I wouldn't worry about losing a few..
Right now, my goal is to get into mid 10's with a naturally aspired small block and can't afford to just give away 20 - 35 HP..

 

I like Oliver, good guy....no patience , but a good guy

 

Quit being a sissy and run that trans brake You might be suprised what will happen...one way or the other

 

Wait a minute! This is the guy that had someone else fix a blown power valve in a Holley carburetor right? Now you can't find the governor cover on the side of a transmission but you're going to have a 1000 hp race car in 2 years? This I gotta see.

The shows just starting folks!

Later.....

 

Might use the transbrake tomorrow.. I first want to get a problem free pass in before using it....

 

Whattya mean, no patience, he lays tons of floor tile every day, that is patience if ever was....

Go and stick your stupid comments up your a**!
I can't remember any low 11 second time slips from you in your Vette! Not everyone who has a fast car needs to be, nor is a master mechanic! I'm doing and did all the major work on my car, but don't get too much into internals. There a doubters on whatever I do, but I've always proven them wrong. When I had my old 383 and my 5-speed and I was running mid 12's, lots of people predicted that I'll never get into the 11's... and guess what, I ran 11.60's with the exact same setup after tweaking it a little.
Right now, I have one of the fastest (if not the fastest) street driven, naturally aspired small block C3... I will hit 10's with that setup and shooting for low 9's or even 8's if I'l go with a blown big block in a couple of years... And guess what, I'll always achieve my goals! I always have!
Come on and show the track results with your Vette or STFU

 

While I don't agree with alot of the stuff you do Oliver I admire your spirit. Through it all you keep plugging away to reach your goal. I admire that. I read all your posts lately because I hope you achieve your 10 second runs and I believe you will/hope you will.
Also the thoughts of you putting a 1000 horse blown bigblock someday down the road appeals to me. I hope I can give you good advice when it comes to a blown bigblock.
I have been in the 10.2 range years ago and lost my complete desire to pound on a race car but through you I can relive part of it again.
Good luck Oliver with the transmission, racing this week and the whole project and keep the meaningful post comming.
I will follow every one of them :

 

Thanks Norval,

I do a lot of things different than other people. I don't care for looks or detail of many things as long as they work. I do a lot of research on whatever I do or put into my Vette. I set myself goals and do whatever I need to do to get there...
I don't have a exact time frame for the big block project yet, but I expect this to happen in 2 - 3 years.. Gonna buy a C6 Vert in '07 and I'll have to see how much $ I'll have left for the big block project.. The expected budget for the big block conversion will be somewhere in the $15k - $20k range...
