 Subject: Over Reving after TB Mod
IP: Logged
Message:
I put on a V8 TB awhile ago and ran into several problems. I first posted about the error code 0455 but I have my fingers crossed it is fixed with a new gas cap. Still when I get on the gas, even after 230miles of break in, it shifts cleanly through 1st and 2nd but then seems to miss third and my rpms shoot up so I back off the gas. Should I just wait longer to break it in or is there a problem with with something?
any help would be great, thanks

It requires no break-in period and it should never required that you reset your computer. Most likely your tv cable is out of adjustment. This is often caused by accidently bending the cable bracket or it was bent when you got it. Did you use the original bracket or one that came with the tb?

I used the bracket that came with the V8TB. What is the TV cable and how can I adjust it to fix the problem? The bracket did not look bent but im guessing that if it was out even a little bit then it could cause the problem.
thanks

GENERAL INFORMATION
The transmission throttle valve is operated by the valve body throttle lever. The throttle lever is actuated by a cable connected to the engine throttle body lever. A lock button at the engine end of the cable provides for cable adjustment.
A correctly adjusted throttle valve cable, will cause the throttle lever on the transmission to move simultaneously with the throttle body lever from the idle position. Proper adjustment allows simultaneous movement without causing the transmission throttle lever to move ahead of, or lag behind the throttle body lever.
CHECK
Turn ignition key to OFF position.
Remove air cleaner.
Verify that throttle body lever is at curb idle position. Then verify that transmission throttle lever is also at idle (full forward) position.
Slide cable off attachment stud on throttle body lever.
Compare position of cable end to attachment stud on throttle body lever:
Cable end and attachment stud should be aligned (or centered on one another) to within 1 mm (0.039 inch) in either direction.
If cable end and attachment stud are misaligned (off center), cable will have to be adjusted as described in following procedure.
Reconnect cable end to attachment stud. Then with aid of a helper, observe movement of transmission throttle lever and lever on throttle body.
If both levers move simultaneously from idle to half-throttle and back to idle position, adjustment is correct.
If transmission throttle lever moves ahead of, or lags behind throttle body lever, cable adjustment will be necessary. Or, if throttle body lever prevents transmission lever from returning to closed position, cable adjustment will be necessary.
PROCEDURE
Turn ignition switch to OFF position and shift into Park.
Remove air cleaner.
Disconnect cable end from attachment stud on throttle body.
Verify that transmission throttle lever is in idle (full forward) position. Then be sure lever on throttle body is at curb idle position.
Insert a small screwdriver under edge of retaining clip and remove retaining clip.
Center cable end on attachment stud to within 1 mm (0.039 inch) and release cable button.
Install retaining clip onto cable: housing.
Check cable adjustment. Be sure transmission throttle lever and lever on throttle body move simultaneously and as described in cable adjustment checking procedure.
