I have a 1983 200-4r that a fella wants to use in his 87 Chevy El Camino. It also has a 200-4r.
Is there a difference with the wiring and lockup applications thru the years?
This one has only 1 wire to the tcc lockup solenoid and I thought I'd seen 2 or more wires somewhere.

Thanks for any info.

200r4

He actually has a better transmission in the '87 and it is more desireable for a performance build.The earlier 200R4's had lubrication issues that make them more prone to failure which were corrected in late '86 and later 200R4's.If the '83 is working OK and you need it to get by use it,but hang on to that '87 core.

I found it has a 7 vane pump.
I will upgrade it to 10 vane.
Will that help some of the lubrication issues?
Still need to know about the lockup wiring.
Anyone?

Forgot to mention, its for a 70 year old guy driving a stock Chevy, no mods.

The 10 vane pump will even out the pulsation but you need to go a little further than a 10 vane pump. I suggest you take a look at CK performance Chris wrote an extensive manual on the 2004r and it was worth every penny.

Yes, the wiring and Solenoids are different, 1 and 2 wire. The 83 trans came from a Non/computer car. 87 will have more wires as the computer controls lockup. You can just swap the lockup solenoid and harness from the 87 to the 83. Tho' I would install a new solenoid, filter and any seal you can get to before installing the trans.
Computer controlled external plug on 87 trans>>
Pin A = 12Volts to solenoid
Pin B = 4th Gear Pressure Switch
Pin C = 3rd Gear Pressure Switch / ( May not be used )
Pin D = Ground

Pin A = Purple is always live +12V to the L/U solenoid
Pin B = 4th gear switch Lt blue feeds the computer Ground when the Trans is in 4th gear.
Pin C = 3rd gear switch Dk grn/white feeds the computer Ground when the Trans is in 3rd gear. ( This Wire may Not Be Used )
Pin D = The computer feeds tan/black -/ground to activate the L/U
( Wire colors may be different )

Pin arrangement on plug Clockwise rotation>>
AB
DC
As stated the 87 core has more upgrades, Hardened Stator & Sun Shell, improved fluid drainback at front seal, Pump bushing Bore has a step to prevent bushing from walking forward & eating seal etc..
Unless you know how to build a Pump and have a lathe, leave the 7-vane pump alone. It's not as simple as just swapping the Rotor & Slide. The 7-vane actually has more volume. It can be slightly noisy but doesn't affect operation. Many have gone back to using the 7-vane. Good pump Info about 3/4 way down page. > http://www.ptsxtreme.com/faq/display_faq.asp?faq_id=4

Thanks SSedan.

Good read.

I was checking my "guide" and it shows a bore plug instead of a valve line up. This unit has valves instead of the plug.
Will this still work after changing the wiring?

You lost me? Do you mean it has a hydraulic style TCC lockup instead of electrical?

No, its electrical.

Explaining on a keyboard is not so simple.
I better take the long way.
I'm using the ATSG service manual.
The drawing for the valve body shows a plug for the convertor clutch t.v. bore.
The 83 200-4r has a valve line up in this bore.
I believe they eliminated the valve line up and used a bore plug for ECM controlled lock up cars later. Same idea as the 700r4 until the bore on that was eliminated completely.

So, with an ECM controlled lockup car and a non ECM convertor clutch T.V. bore valve line up instead of the bore plug will the lockup still function properly?

Still hard to get this across....

Ahhh, I see. I haven't seen an older 2004R in a good while. You're talking about #348 on Valvebody. On those the Pump Stator/Cover and the regulator valves are also different. Honestly I'm not sure since I haven't swapped in an older one. I think it will work but, Crosley would know for sure, maybe he will chime in on this.

The Stator/Cover is the pump half that the solenoid & pressure regulators are housed in, which you probably know.
This is from the link I posted above>>>
((There are two stators used. 150 casting is 81-82, and 088 is casting for 83-90. There are 3 pump bodies used : last 3 casting numbers, 149 (81-82), 082 (83-86) and 690 (late86-90). The 150 casting pump stator will only work with the 149 casting pump bodies, and vice versa. The pressure regulator valves will only work with corresponding pumps too. The valve with a solid valve, no hole, will only work in a 150/149 combo. The valve with the hole will only work in the 088 casting stator. If not, severe pressure problems will result. The 088 stator and both the 082 and the 690 pump bodies will interchange.))

#348 is the one.

The valve body in it now has a plug where the the 4th clutch switch goes.

I'm wondering with the valve line up this has, will a 4th clutch pressure switch be activated if I install it where the plug is.

If thats the case, it should work with a wiring swap.

Found this on Donny Wangs site >> (Beginning late in the 1982 model year, the THM 200-4R transmission control valve assembly was changed to eliminate the Torque Converter Clutch Valve Train. The computer command control unit controls the converter clutch making the torque converter clutch valve train unnecessary. A new solid plug replaced the control valve assembly to direct oil flow.)

If the plugged 4th Press. switch port on VB doesn't work, there's an external 4th pressure port of the passenger side of trans to the rear of the Servo. That can be used to operate 4th gear only TCC lockup. Just needs a pressure switch & wiring installed there.

I got no way to know unless I installed it and found out it wasn't working :drunk: ....hmmmmm...must be a way to figure it out.

The guy who wants it needs a plug and play so I'll have to find another core.

Thanks,
Pugsy
