Shift to drive, hit gas, 3 sec delay.....

[bstone]

For the past few weeks I have been noticing a very short delay when shifting from reverse to OD. It will take a brief second until I feel OD "engage". Tonight, after leaving EMT school, I shifted from Reverse to Drive, hit the gas and nothing for almost 3 seconds. The engine revved, but I did not move forward for 3 seconds.

This is the *third* tranny in my 93 Explorer XLT. The first AAMCO rebuild died less than a year after they put it in. This tranny is just over 1.5 years.

I checked the fluid and it's red and up to a proper level. I had it flushed before the summer began.

I beg for ideas. Thank you.

Check the fluid level first, low fluid level will do this same thing.

I know you said you checked it but the dipsticks can be really hard to read and the fluid will also tend to settle down a bit if you let it wamr up, idle, have the truck parked on level ground, then check it again.

Did the shop doing the flush use the correct type of fluid?

There is a decent chance it is the sealsoin the low/reverse servo piston. They can be replaced from under the car without removing the transmission. Other leaks can manifest themselves as a slow fill of the low reverse servo resulting in a delay. The good news, is that it isn't hurting anything so long as you be patient and let it engage before you get on the gas.

Thanks for the replies. I checked the level of the tranny fluid today before turning it in. The truck had been sitting for almost 2 days unused at this point. If anything, the fluid is well above the x.. on the dip stick. I certainly don't recall adding that much fluid. I wiped the stick and looked again, same thing. Fortunatly, the color of the fluid is red.

After getting to school and going from reverse to forward, I had the same issue but not as pronounced.

Ideas?

A delayed engagement could be from a few areas. You could have low line pressure, a clogged filter, dirty valve body, loose valve body bolts, improperly adjusted bands, bad servos, bad seals, and/or O rings, etc. Without getting too overboard on every part, the first step is to use a transmission pressure gauge to see your pressures at different points. Check the sticky about using a pressure gauge.
