What does the vacuum modulator do on a Turbo 350?
The vacuum modulator is a vital component of automatic transmissions. It tells the transmission what kind of load is being put on it, allowing the transmission to react with the proper line pressures and shift points.
How does a TH350 transmission work?
The low sprag is engaged and power flows through both planetary gearsets. When the transmission shifts to second gear, the intermediate clutch is engaged, the forward clutch stays engaged, the low sprag freewheels, and the power flows through only the front planetary set through the intermediate sprag.

What does a modulator do on a transmission?
The vacuum modulator is a vital component of automatic transmissions. It tells the transmission what kind of load is being put on it, allowing the transmission to react with the proper line pressures and shift points. Over time, modulators can develop leaks, suffer ruptured diaphragms, become bent, etc.
What kind of transmission does a GM TH350 have?
GM TH350 Automatic Transmission The TH350 is an automatic shift, three-speed transmission. It is widely considered to be one of the greatest of automatic transmissions ever built. The TH350 transmission was introduced in the 1969 model year as the successor to the GM Powerglide automatic transmission.
How do I know if I have a TH350 or TH400 modulator?
This modulator has been stationed at the transmission’s side and there may be a rubber vacuum line connected to it. You’ll know it’s the TH350 if you have the fitting attached to the right frontal side of the transmission. However, it is the TH400 if this fitting is at the transmission’s front-rear side.
Where is the vacuum modulator on a Ford TH350 transmission?
This modulator has been stationed at the transmission’s side and there may be a rubber vacuum line connected to it. You’ll know it’s the TH350 if you have the fitting attached to the right frontal side of the transmission.
What is the code for a th350c?
The TH350C had codes of MV4, MX2, MX3 & MX5. There were downsized derivatives of the TH350, designated TH200, TH200C, TH250, TH250C & TH375; a beefed up Buick version.
