Is there a lock up torque converter on a 518?
Remember overdrive is only 3rd gear high range anyway. There are two wire 518 transmissions out there; these have a non-lock-up torque converter. With this three wire setup you have a four speed transmission plus a torque converter lock-up feature.
When do you lock up the transmission on an A518?
Lets say you’re in overdrive going 54 miles per hour at very light throttle, when you press on the throttle and the vacuum drops below 3 inches the transmission will immediately shift back to 3rd gear low range without lock-up or even a lower gear depending on the throttle position. #3.
What happens when the toggle switch is turned on on an A518?
When the switch is turned on you will have 1st, 2nd and 3rd gear low range plus 3rd high range. When the toggle switch is on the transmission will immediately shift into overdrive at light throttle over 44 miles per hour whenever it’s in drive range on the gear selector.
Where are the ground wires on a 518 transmission?
The center wire on the transmission is the hot wire and the two other wires are ground wires for overdrive and the lock-up torque converter. The front wire is the overdrive ground and the rear wire is the torque converter lock-up ground. You can get a three wire female connector from a junk yard or buy one from us.
Where can I find an A-518 overdrive transmission?
You can locate the A-518/46RH transmissions in these donor vehicles: When finding one of these units, it’s wise to take the shifting linkage in the case of a column-shift vehicle or the floor shifter because linkage on the A-727 is not exactly the same as the A-518 and requires modification.
Can a three speed transmission be replaced with a 518?
This is how to replace your three speed 727 transmission with a 1995 back A518 overdrive transmission with a three wire connector (gas). A 518 transmission has a 31% overdrive and will produce a 30 to 40% increase in gas mileage on the road over a three speed transmission.
Lets say you’re in overdrive going 54 miles per hour at very light throttle, when you press on the throttle and the vacuum drops below 3 inches the transmission will immediately shift back to 3rd gear low range without lock-up or even a lower gear depending on the throttle position. #3.
