All Turbo-Hydro 400's are not the same, do you want your Rolls to feel like a Chevrolet or a Rolls Royce?

1990 Rolls Transmissions we use for the Cloud conversions to replace the old GM 4 speed Hydra-Matic used in the Cloud & Bentley vehicles.  This Transmission is the correct size to clear the original Rolls Transmission mounts with out cutting brackets off the Rolls frame.  Chevrolet Transmission is a poor choice, even though it will fit the engine it will not fit the chassis correctly, this works a LOT better.

NEW: TH400 housing with smaller & shorter bell housing.
This also allows required space for the adapter with the Cloud Motor-Mounts & retains correct converter spacing.  We also have the correct out-put flange to connect to the Cloud drive shaft with the larger "U"-Joint. We install the correct components to match the weight & HP of the conversion on your specific vehicle.  This allows the best shifting feel & reliability.

Check the pump passage's at the bottom of the picture.
This is part of the reason we selected the Rolls Automatic
over the standard Chevrolet TH-400 Automatic.

NOTE: We have the best Brake Conversion for your swap available with out question.
Our conversion accommodates the extended 3.5" master cylinder travel required due to the lack of brake shoe adjustments on Cloud vehicles.  We also eliminate the 18" lag & supply the required 2,000# hydraulic pressure.
