I have a toyota 5fbe15 forklift set at 36 volts. The problem i'm having is that every now and then, it will shift at normal speed, 5-6 mph and slow to 1 mph. Usually happens if it's shifted from foward into reverse while holding the accelerator down. It eventually corrects itself somehow and operates normally. Does this need to be serviced or is there a loose connection somewhere? Thanks

Any codes?

Is it the engine vibrating or the car? If its the car itself it sounds like u need to have the tires checked & balanced.

the chain is to tight when you put it into gear you loose 2-3 links of slack and if its to tight you cant change gear move the back wheel closer to the swing arm that should fix it

hope this helps

it will be the electrical item in line from your air filter housing to the engine intake manifold, normally part of the lid or in the pipe. With at least 4 wires coming from it. Hope this helped..

Hello. Welcome to FixYa. I am Toyota Ed, and I will be assisting you today.

The Overdrive function allows the transmission to shift an extra time, sort of like selecting 5th gear in a 5 speed manual transmission. The Overdrive, when used, will save you gas, as the engine is no longer maintaining a high RPM at normal driving speed. Look at the tach whilst driving about 45 mph, and engage/disengage the OD. You will see the tach RPM raise when the OD is off.
More RPM = lower fuel mileage,

The ECT is a different circumstance. The ECT button is used primarily when you have a heavy load in the car, or are towing something. All the ECT button does, when it is engaged, is lengthen the shift points as the transmission upshifts. Normally, the transaxle will shift into 2nd gear at 18-21 mph. When the ECT is engaged, the transaxle will shift in the area of 22 -24 mph. In short, the ECT just makes the time to the 1-2 and the 2-3 upshift longer, to compensate for the additional load being carried/towed.

I hope my assistance answers your question.

Thanks for choosing FixYa today!

Never heard of that one. You can change the speedo gear in the trans attached to your vehicle speed sensor. More teeth slow the speedo down. count the teeth on the one in there and see what the dealer has. about $5 each.

He may not have known to put it in tow mode and doesn't want to get blamed for damage to transmission towing it in wrong gear.

When the car is just cruising along at approx.50+ MPH push the O/D button. You should feel the gears change higher and if you have an RPM guage then it should drop as well to fewer RPMs. This would be normal driving conditions. O/D will not kick in until the last regular gear (3rd or 4th depending on model)  had been shifted into. O/D automatically kicks out when slowing down and the transmission shifts to a lower gear. Thus the O/D has no function at slower speeds/gears and does not need to be shifted ( on or off ) except in the very first example given here.

That is normal,If you do the same speed in 4th gear the rpm's will almost double.

The rpm's will repond faster in a manual than an automatic.

In a manual the engine supplies the power required directly to the gear that you have selected thus the engine rpm's will increase or decrease as needed.

Could be a solenoid in the tranny, or the throttle position sensor need calibrating.
