200-4R Swap Questions

[krcotter]

I found a 200-4R out of a 1985 Monte Carlo with a 305 V8. I want to install it into my 1970 C10 and replace the TH350. I have a 350 CID motor, and everything else should be standard.

I found a tranny shop willing to do my swap, I just don’t have the time, tools, or skill to do it myself. The shop suggested I get as many of the swap parts as I can, to help speed things along. Here’s what I’ve got.

Lokar - Column Shift Linkage ACA-1800
Lokar - Hi-Tech kickdown kits KD-2200RHT
TCI - Lockup Wiring 376600
TCI - Replacement Lockup Solenoids 376601
Superior - Shift Reprogramming Kit 200-4R HP

QUESTIONS:
I’m wondering if you guys out there know what I can/should do as far as the shift indicator?
Do I need some sort of speedo/governor gear swap as well?
Anything I’m missing?

go back to the car and get the tv cable and bracket on the intake and the carb, or at least the pin the tv cablr connects to and a good clear photo of where it is mounted on the throttle linkage..

There is no kick down cable, so no idea what that lokar kit is..

The 83/84 monte ss had a 3.42 gear gear and a 26" tall tire
the 85-88 had 3:73 gears and a 26" tall tire.. this will help tell you how far off your speedo will be..

if running a holley carb they make a 2004r cable connector to put on the throttle linkage, same with edelbrock..

If you can't get the tv cable parts off the doner car you'll need to get them..
one that mounts to intake and the other for the carb..

And it must be set correctly!!!!!!!!!!!!!!!!!!!! this is life or death of your trans..

The 2004r used the same yoke as the th350 you are replacing, and will require moving the truck transmission crossmember back a little..

Replace the converter, the oem lock up clutch most likely is on last leg.. not worth using it.

I'm planning on having the 200-4R rebuilt and a new torque converter is a no-brainer.

I no longer have access to the Monte Carlo. I have a Jegs Intake Manifold (555-513000) with an Edelbrock 1403. The Lokar cable is a fancy TV cable for the 200-4R. Maybe I should just order all the bracket stuff I can find online.

85-88 had 3:73 gears and a 26" tall tire, great do you know what the standard rear end gear was on '70 C10.

no idea what was standard for a 70 c-10
mine had 3.07 gears..
The bonus with the 2004r is no need to cut the drive shaft..

I have a v8 out of a b-body so I have the oem brackets, but I also bought the aftermarket adjustable parts just in case..

the
holley part for the carb is #99r-2110-3 sometimes listed as 20-121 (for holly carbs)
The b body v8 has a ccc q-jet with the tv connector on it that I can use if I run the 75 truck q-jet I have..



the adjustable(to make up for different intake heights) bracket to mount to intake..
edelbrock #8032

The oem brackets and connector for the t.v. cable will be on
v8 g body's with 2004r
v8 b body's with the 2004r or 7004r including wagons and full sized caddy's.
v8 ccc q-get v8 f bodies with the 7004r some 82 and most 83-85
80's truck with v8 q-jet and 7004r..
The tbi v8's brackets might be the same have not compared.

does not matter if the brackets come from a ccc q-jet 4.3 v8(not the v6) 305 or 350 the 4.3 v6 brackets might be the same but again have not compared,, but the cable would be shorter..

I had my tilt column which I ordered around the same time to be built with a 4 speed lens, which they did. So if he can find them for Tilt, they must be out there for regular columns as well.

I will throw out that the cooler lines are reversed on a 200 vs a TH400. Don't know if it matters (might still work just fine backwards through the radiator) but isn't optimal unless you swap them, but verify in case my memory is bad on this one.

Otherwise a pretty simple install because the length is so close to your original. It's a bolt-in for a powerglide or TH350.

Don't underestimate the importance of the TV cable. Is it NOT a kickdown. It controls line pressures inside the trans (like how hard clutches press together) and it will shred the guts of your trans if it's not adjusted properly (or left unconnected). Don't attempt to drive it without that.

Why gm made these units depend on that very touchy cable adjustment for working is beyond me,all it does it make a inherently weak trans even weaker. I will never run one of those vs a th350 or Th400. Id rather run a bit less gear and keep it strong and simple. Ive seen so many burnt 700r4's its silly.

If you haven't, I would also read this:

http://www.bowtieoverdrives.com/Inst...GUIDELINES.pdf

I installed one in my '69 Suburban and it worked out good. The first one I had a guy gave me and it turned out it was bad. The second one I got from a local salvage yard and it worked good. Another thing, do not use a 3.07 rear end with the 2004r, it is to high of gear for the OD, the trans will overheat. A 3.73 is about right.

My 200-4R lived nicely behind a ZZ502 in a 4200lb car with slicks. They're a fine transmission when properly built but need to be set up correctly as you note.

The adjustment isn't really touchy, it's pretty trivial when you've got a factory linkage setup, really. The problem is we try to use them in other applications without factory linkage brackets and people do a poor job of it, then they burn out and people call them weak.

I'd rather have a 6 speed transzilla, but they're close to $6K I think!

Or one of the new A8s would be really sweet too! I have a 4L80E and could still use a few more gears.

hey LocDoc

I purchased a 71 that po had installed a 200-4r in. The trk is running 3.07 gears. Have not driven much, just around town. If what you say is fact, I will for sure change out the gear ratio.
The transmission was built by Tobbys Trans. shop somewhere in Florida.
813-382-1696 is the ph. # Seems like nice people had get some infor from him once.

Why, you wanna know Why, Well I'll tell ya why..
EPA AND C.A.F.E. REGS..
off the throttle idling like in traffic,, it unloads the engine..
part throttle with less pressure (but enough to not slip at factory rated torque) = less loss at the pump as higher pressure takes more h/p torque..

And why the 2004 in the Ss had different parts and the gn had different parts. it was set up for the power the engine made, and give the best mpg, epa emissions and c.a.f.e ratings..
same thing was done with the 7004r with different parts in the f body and different parts in the vette..

This is the same reason they went to electronic control.. it does the same thing, but doesn't require a cable that stretchs that no one checks /adjust at service intervals like g.m. called for..

Nothing wrong with this trans other than they were designed when v8's and v6's didn't make much power.
And need stronger parts added when used behind hotter engines.
no different than putting a th350 behind a bbc.. you would not do that and rebuild it as stock.. as it was not designed to take that type loading..
There is a reason g.m. never backed a big block with a th350..

The 2004r and 7004r get a bad rap because peope stuffed them in for the o/d without upgrading parts, and had no clue on how to set up and check the tv cable..
most that burnt them up had the tv cable on the th350 downshift part of the carb linkage.. a no no..
