Transmission does not smoothly shift from first to second gear
1998 ISUZU RODEO
Does not smoothly change from first to second gear. Hoping filter change could correct the problem. What would you suggest or hard would replacing filter be?
have the same problem?

It depends on what is actually causing the shift issue. A sticking solenoid or valve in the valve body might be helped with a fluid change. However if it is due to worn parts a fluid change may actually make it worse.
The issue is that your vehicle uses a "sealed for life" transmission. Real stupid idea but they thought it was great.
To do a fluid change, no filter in the transmission just a screen.
Place a large drain pan under the transmission pan.
Remove the transmission oil drain screw and drain fluid.
Tighten drain screw to 38 Nm (28 ft. Lbs.)
Accurately measure the amount of fluid you removed from the transmission.
Remove the transmission overfill screw and fill transmission through overfill screw opening, using DEXRON III ATF.
Add transmission fluid until you have added in the amount that you removed.
Tighten overfill screw to 38 Nm (28 ft. Lbs.)
IF you have a scan tool that can read the transmission temperature :
Let engine idle until a fluid temperature between 32 C (90 F) and 57 C (135 F) is reached.
Add transmission fluid until it flows out over the overfill screw opening.
Tighten the overfill screw to 38 Nm (28 ft. Lbs.)
