wickiewicked240z Posted August 27, 2008 Share Posted August 27, 2008 It's a 1999 Chevy S10 4x4 automatic transmission. This past week it started acting up. Traveling around 70mph around 2000rpms if I try to go any faster the RPMs will go up 200rpm's and then back down while pressing the accelerator. Like if the overdrive was going IN and out. What could be the problem? bad solenoids? Quote Link to comment Share on other sites More sharing options...
m4xwellmurd3r Posted August 27, 2008 Share Posted August 27, 2008 sounds like the bands are getting worn? we had a 1993 blazer 2wd that did that and had to get the transmission replaced (instead of rebuilt we swapped it with a newer unit my uncle had) my 1990 bronco II's overdrive was totally shot, then it got worse and if starting from a stop it would act like it's in neutral and rev to the limiter then launch. eventually the transmission went 100% dead. your transmission is on its way to a rebuild. stop using overdrive and take it easy till you can rebuild it.
