Transmission adjustment

Need advise; My 93' Ranger XLT extra cab 2wd, 4.0 engine and A4LD auto tranny with 126,600 miles has a rough downshift into 2nd gear about 15 or 16 mph. Down shift to 1st is real smooth and upshifting thru the gears is smooth. I just put a new modulator valve on it and it helped the upshifts smooth out, they were getting to be hard shifts before changing that valve. I do not know if there is any adjustment that can be made to smooth out the rough downshift when slowing down to a stop for red light. The U-joins are in good shape and new carrier bearing assembly on driveshaft and no extra play in the rear end. A band adjustment maybe or just have to live with it.

There is no band adjustment to be made. The rough shift is due to excessive wear and clearances. When was the last time you replaced the fluid?

Hi Khan; I changed the fluid and filter about 800 miles ago, used Mercon V. Yeah, that is the only glitch with the truck the rough down shift on 2nd gear. Every other upshift and downshift is smooth.

Sounds like you have a solenoid issue. The rod eggs out the case. The new cases have a brass insert. I would take a look anyway.

I ended up doing a band adjustment on the rear one; backed off a few turns and it is downshifting real smooth now and the upshift is also smoother so I am good with it. Thanks for the info.
