How much horsepower can a 700R4 transmission handle?
The Street/Strip 700R4 is good for about 550 hp maximum, but with the HD input drum it is good for about 625 hp max.
Which transmission is better 700R4 or 4L60E?
If the transmission has a large 18-pin electronic connector above the passenger side pan rail, it’s a 4L60E, as seen here. If it has a cable connection near the cooler lines on the passenger’s side, that’s a 700R4. The good news is that either way, you win.
How strong can a 700R4 be built?
In the process, we kept digging deeper into the world of 700s and discovered several more things that can be done to the R4, as well as things that shouldn’t be done. For example, Team Ramco’s “Flashman” Sharrar says that they can be built to withstand up to 850 hp and 600 lb-ft of torque.
Can you run a 700R4 without a computer?
To run a 700-R4 trans behind a carbureted engine without a computer, at the very least the TV cable must be hooked up to the carburetor and properly adjusted. Not just a simple kickdown cable like your TH350 analogue, the TV cable controls line pressure and shift points.
What does the TV cable do on a 700R4?
The TV cable on the 700-R4 and 200-4R transmissions controls line pressure, shift points, shift feel, part throttle downshifts, and detent (full throttle) downshifts. So if the TV cable is not adjusted properly, it can cause numerous transmission problems.
Can you replace a 700R4 with a 4L80E?
No, neither the 4L60E or 4L80E will directly swap in. Your 4L60 or 700R4 is a hydraulically shifted trans with an electric lockup in it where as the 4L60E and 4L80E are both fully electrically shifted.
Can I put a 4L60E in place of a 700R4?
No 700R4 transmissions were ever controlled by the ecm. The lockup function is grounded with the ecm, but not the shift points like the 4L60E that replaced it. Any 700R4 will work in any application.
Can 700R4 handle 454?
Yeah a stock 454 won’t kill a stock 700r4 unless you’re planning on towing with it or hot rodding the 454 some day. Once you upgrade something though you’ll have a hard time with the weak parts like planetary, power band, output shaft.
Will a 700R4 bolt up to a LS engine?
The 700R4 will bolt up to the LS1, except for one bolt, leave it out.
