i have a 98 durango and the 1 to 2 shift is way late the rest are right on time. just changed fluid and filter

 

What engine? 5.X need to have bands adjusted. 4.7 no bands.

 

need more info, engine, transmission, any idiot lights on? what else have you done?

 

i have a 5.2 , no light on no codes haven't done any thing else.

 

master tech will give you a definite answer, since this is his specialty (transmissions)

but i would start by have the fluid and filter CHANGED, and the bands adjusted (do them together since you need to drop the pan for both, sorry to hear you just did the fluid, sounds like they missed a step)

also make sure that the TV (kick down) cable is adjusted properly, i dont think it would affect upshift points, but ya never can tell.

 

TRANSMISSION THROTTLE VALVE CABLE ADJUSTMENT
The transmission throttle valve is operated by a cam on the valve body throttle lever. The throttle lever is actuated by a cable connected to the engine throttle body lever A retaining clip at the engine-end of the cable is removed to provide for cable adjustment. The retaining clip is then installed back onto the throttle valve cable to lock in the adjustment.

A correctly adjusted throttle valve cable, will cause the throttle lever on the transmission to move simultaneously with the throttle body lever from the idle position. Proper adjustment allows simultaneous movement without causing the transmission throttle lever to move ahead of, or lag behind the throttle body lever.

THROTTLE VALVE CABLE ADJUSTMENT CHECK
Turn ignition key to OFF position.
Remove air cleaner.
Verify that throttle body lever is at curb idle position. Then verify that transmission throttle lever is also at idle (full forward) position.
Slide cable off attachment stud on throttle body lever
Compare position of cable end to attachment stud on throttle body lever:
Cable end and attachment stud should be aligned (or centered on one another) to within 1 mm (0.039 in.) in either direction.
If cable end and attachment stud are misaligned (off center), cable will have to be adjusted as described in following procedure.
Reconnect cable end to attachment stud. Then with aid of a helper, observe movement of transmission throttle lever and lever on throttle body.
If both levers move simultaneously from idle to half-throttle and back to idle position, adjustment is correct.
If transmission throttle lever moves ahead of, or lags behind throttle body lever, cable adjustment will be necessary. Or, if throttle body lever prevents transmission lever from returning to closed position, cable adjustment will be necessary
Throttle Valve Cable Attachment - At Engine
THROTTLE VALVE CABLE ADJUSTMENT PROCEDURE
Turn ignition switch to OFF position and shift into Park.
Remove air cleaner.
Disconnect cable end from attachment stud on throttle body.Carefully slide cable off stud. Do not pull or pry cable off.
Verify that transmission throttle lever is in idle (full forward) position. Then be sure lever on throttle body is at curb idle position.
Insert a small screwdriver under edge of retaining clip and remove retaining clip.
Center cable end on attachment stud to within 1 mm (0.039 in.)
Install retaining clip onto cable housing.
Check cable adjustment. Be sure transmission throttle lever and lever on throttle body move simultaneously and as described in cable adjustment checking procedure.


Welcome to DF
Most likely cause for a late or too early shifting problem would be the throttle cable adjustment, thats for either the 44RE and 46RE transmissions.

 

You have a 44RE transmission.


Dan<------In 1998-1999 the 4.7L was never installed. It was 5.9L, 5.2L in 1998 and 3.9L added in 1999.

In 2000 the 5.2L was replaced by the 4.7L and 3.9L/5.2L was removed from production.

From 2000-2003 it was 5.9L and 4.7L with 35% or so in 5.9L

 

hydra, in 2000 the 4.7 replaced the 5.2 in the 4x4's ONLY, in 01 the 5.2 was completely replaced by the 4.7

 

I stand corrected! http://consumerguideauto.howstuffwor...ge-durango.htm
