2WD Transmission Swap Information

Swap a 350 transmission with a six inch tail to a 700R4 transmission:

#1. The drive shaft will need to be cut three inches.

#2. The cross member will need to be moved two or three inches.

#3. The passing gear cable bracket on the motor can be reused.

#4. The passing gear cable connection on the carburetor can be reused, if you have the original carburetor.

#5. If you have a Holley or Edelbrock carburetor you need a carburetor adapter.

Our #29. 700R4, adapter for a Holley or Edelbrock carburetors to install the throttle valve cable correctly. Usually this part will correct a hard light throttle 1-2 shift. With this kit getting the correct geometry is easy. If you have a 700R4 transmission and one of these two carburetors you need this part.

#6. You will need a new 700R4 throttle valve cable and dip stick.

#7. The shift linkage can be reused. D will be OD, 2 will be D and 2nd and 1st will be to the left and right of the 1.

#8. If you have a 350 transmission now with a nine inch tail the drive shaft will not need to be cut.

#9. The drive shaft yoke is the same on both transmissions.

#10. The 350 vacuum line will need to be removed. The 700R4 transmission doesn't need vacuum.

#11. The cooling line positions stay the same. The auxiliary cooler always goes in the top return line on a 700R4 transmission.

#12. If you want the torque converter to lock-up you must in install a lock-up kit in the transmission pan. On 1982, 1983 and early 1984's with a 27 spline input shaft you must install a lock-up kit or the transmission may burn up. Our part #12.

#13. This is an adapter plate to install the 700R4 transmission on an Olds, Buick or Pontiac motor. Our #15.

Swap a 400 transmission with a four inch tail to a 700R4 transmission:

#1. The drive shaft will need to be cut and a smaller yoke installed.

#2. The cross member can be used in the same location, if you use a special 700R4 tail housing.

Our #49 700R4 tail housing with transmission mount (7 3/8 inches long). This will move the mount to the rear 5 1/2 inches. This moves the rear transmission mount to the same position as a TH400 transmission with a 9 inch tail housing and 32 spline output shaft. The TH400 9 inch tail housing with the 27 spline output shaft has the same mount position as the 4 inch tail housing. With some modification to the 2 mount bolt holes on the crossmember this extension housing can eliminate crossmember modifications when replacing a TH400 with a 4 inch tail, 9 inch tail with a 27 spline output shaft or 200-4R transmission with a 700R4 assembly.

#3. Will need a throttle valve cable bracket on the motor.

Our #8X. Universal Throttle Valve Cable Bracket.

#4. You will need a way to connect the throttle valve cable to the carburetor. If you have a Holley or Edelbrock carburetor use #29 above.

#5. You will need a new 700R4 throttle valve cable and dip stick.

#6. The shift linkage can be reused. D will be OD, 2 will be D and 2nd and 1st will be to the left and right of the 1.

#7. The 400 vacuum line will need to be removed. The 700R4 transmission doesn't need vacuum.

#8. The cooling line positions stay the same. The auxiliary cooler always goes in the top return line on a 700R4 transmission.

#9. This is an adapter plate to install the 700R4 transmission on an Olds, Buick or Pontiac motor. Our #15.

#10. If you want the torque converter to lock-up you must in install a lock-up kit in the transmission pan. On 1982, 1983 and early 1984's with a 27 spline input shaft you must install a lock-up kit or the transmission may burn up. Our part #12.

Swap a 200-4R transmission to a 700R4 transmission:

#1. The drive shaft will need to be cut three inches.

#2. The cross member can be used in the same location, if you use a special 700R4 tail housing. See #49 above.

#3. The throttle valve cable and motor bracket can be reused.

#4. The throttle valve cable connection on the carburetor can be reused, if you have the original carburetor.

#5. If you have a Holley or Edelbrock carburetor you need a carburetor adapter. See #29 above.

#6. You will need a new dip stick.

#7. The shift linkage is the same on both transmissions. 

#8. The drive shaft yoke is the same on both transmissions.

#9. The cooling line positions on the transmission will need to be swapped, because the return line on a 200-4R is on the bottom and the 700R4 is on the top. The auxiliary cooler always goes in the top return line on a 700R4 transmission.

#10. If you want the torque converter to lock-up you must in install a lock-up kit in the transmission pan. On 1982, 1983 and early 1984's with a 27 spline input shaft you must install a lock-up kit or the transmission may burn up. Our part #12.

#11. This is an adapter plate to install the 700R4 transmission on an Olds, Buick or Pontiac motor. Our #15.


#56. Adapter to install a Chevy 700R4 transmission on a Ford Small Block motor. Comes with the flywheel, adapter plate, flywheel adapter, dust cover and bolts. We're an Advance Adapters Dealer. See the AOD page for more details.


Electronic Ratio Adapter (ERA)

Now You Have the Solution to Your Speedometer Problems.....

For 700R4's with electronic speedometers.

ERA

#69. Any change in a vehicle's tire size or rear axle ratio will cause the speedometer reading to be inaccurate. The Electronic Ratio Adapter (ERA) is designed to correct this problem. With the ERA, you simply hook up four wires, set the DIP switches according to the calibration table included with your order, and you are ready to go.

What does the Electronic Ratio Adapter do?

The automotive industry has a great variety of part sizes, types, shapes and descriptions, but regardless of make, model or year, a few things are standard. One of those standards has been the number of revolutions a speedometer cable will make for each mile travelled.  Nowadays, electronic pulses have replaced the rotating cable, but the same principle applies. The Pulse Ratio (the number of pulses per mile travelled) remains the same, regardless of speed, since the same distance is travelled and the same number of pulses have occurred each mile no matter what the speed was during that mile.

However, this Pulse Ratio can be made to vary from the true when modifications are made which change the number of electronic pulses per mile on a particular vehicle. This is most commonly caused by changing the tire size (increasing the outside diameter of the tires will cause the tire to travel further before making a complete revolution), but other modifications could have the same result. When the Pulse Ratio is thrown off, the speedometer/odometer will be inaccurate and corrections must be made.

This relative difference between true speed and the speed indicated on the speedometer is called the Variance Ratio, and it is corrected using the Electronic Ratio Adapter.


GM Ratio Adapter

#54RA. This GM ratio adapter will slow your speedometer cable down 26.7%. Made for low rear end ratios with short tires.
