Why does Turbo 400 slip?
The slipping happens when you are driving or changing gears and may accompany odd noise. Since the primary role of a turbo 400 torque converter is to efficiently convert engine power into hydraulic pressure for the transmission to use for shifting gear, if it is malfunctioning, you may experience slipping in overdrive.
How much horsepower can a Turbo 400 take?
About 400-450 HP/TQ is the limit on the stock TH400. With ONE almost free modification and some minor valve body calibration changes, 800 HP on an otherwise stock TH400 is not a problem if it’s assembled well (good endplay, etc), and the 34 element sprag is a wise addition above 450 HP or any drag usage.
How much torque can a Turbo 400 take?
The TH400 is conservatively rated at 450 ft. lbs. of input torque. Aftermarket building techniques take it well past that figure.
Does a Turbo 400 have a kickdown cable?
When the Turbo 400 began reaching production models in the late ’60s, its kickdown switch was mounted on or near the carburetor. It was, however, relocated to the passenger compartment and mounted on the throttle pedal in later years.
How much weight can a TH400 handle?
In general, the Turbo 400 can be built to handle as much as 500 hp and tow up to 13,000-pound trailers-although not necessarily daily.
Does a TH400 have a passing gear?
I know that the TH400 has an electronically-controlled passing gear with some sort of switch under the dash, but where is the switch and what should I be looking for? The carbeurator is a new Edelbrock Quadrajet, but passing gear never worked w/the original Quadrajet either.
Does Turbo 400 have overdrive?
An overdrive unit is designed to maintain cruising speeds of the vehicle while simultaneously reducing the RPM produced in order to better fuel economy and prevent excess noise and wear made by the various parts of the transmission.
How much longer is 4l80e than TH400?
about 4 inches longer
Also, the 4L80E transmission is typically about 4 inches longer than a TH400 (depending on the length of the extension housing), but the trans mount is located roughly 112 inches rearward.
Is a kickdown cable necessary?
In fact, if you don’t mind downshifting manually with the shift lever when passing, there’s really no need for a functional kickdown cable or switch at all. Even manual downshifting to obtain passing gear may not be needed in the ultralightweight T-bucket’s case because it has so little inertia.
