PASSENGER'S SIDE
DRIVER'S SIDE
Features of Note:
- These two transmissions are together because they were the only ones installed in the Turbo Regals from 78-87. The 350 is the 78/79 style, nonlockup.
- The 350 in black and 200R4 in silver
- The blue tag on the rear of the 200R4 tells the model. The tag is blue because this is an 86 model. 87 has a yellow tag. This one reads CRF, meaning it came out of a Monte Carlo V8. For a Turbo Regal it would read BRF.
- The 200R4 is a one piece body, the 350 has the tail shaft bolted on.
- The 200R4 has a longer body, but overall length is the same.
- The output shafts have the same size and number of splines, allowing the same driveshaft to be used with either transmission.
- The transmission mount for the crossmember is under the very end of the 200R4 and on the 350 it is under the tail shaft housing close to the point which the housing bolts to the body. They are different lengths from the bellhousing and do not interchange.
- The gold canister on the lower rear of the 350 is a vacuum modulator, which is not used on the 200R4. That action is controled by the TV cable.
- The round casting on the side of the 200R4 contains the modulator valve which controls shift firmness especially on the important 1-2 shift. On the Turbo Regal the valve is specific to the BRF.
- The yellow plastic tube on the top center of the 200R4 is a vent. What appears to be a loop on the top of the 350 near the bellhousing is a metal vent tube.
- The difference in bellhousig shape is because the 350 is a BOP (Buick, Olds, Pontiac) and the 200R4 is a univrsal fit.
Features of Note:
- In the center of the 200R4 you can see a yellow plastic loop which is used to hold the wires from the computer to the transmission. They connect to the square plug directly below the loop.
- Near the rear of the pan and on the body of the 35 you see a round cover held in place by a spring clip. This contains the governor which controls shift points.
- Both transmissions connect the speedometer cable in nearly the same
location and should interchange.
BOTTOM
BELLHOUSING
Features of Note:
- The 350 has a square pan with one corner angled off.
- The pan on the 200R4 is much larger and irregularly shaped.
- The smaller area in the rear of the 200R4 pan is where the governor is located in this transmission.
- This picture also shows more clearly that the transmission crossover mount is much farther to the rear on the 200R4.
- The red plug in the corner of the pan on the 200R4 is where it was pierced for draining at the Pick & Pull yard. It was $39 well spent.
Features of Note:
- You can see the multifit bellhousing.
- Also visible is the pump cover, input shaft and the stator support.
- Note that the stator support is the outer part of the shaft and the spines on the support are prone to damage from the power of the Turbo V6.
