1st problem i have is what is it that i need to get to make the abs and brake light shut off??? 2nd the check engine just came on and i hooked the computer up to it and it says 3-4 shift malfunction is there anyway way that i can get this resolved also THANKS FOR THE HELP

I just had the ABS and BRAKE lite thing as well as no speedo below 25mph.
Rear speed sensor, on diff, was problem. Part was cheap, $27, install was simple, less than 10 min.
Speedo worked fine right away, lites went out in 5 min of driving. Woooo Hooooo!!!

I had the check engine lite thing and the eratic shifting thing back in spring , had garage replace transmission speed sensor. Fixed it right up.

My '98 Duh-Rango is like new once again......
