Whats up guys!! first post on yotatech!! I have a 91 V6 3.0 Manuel 4runner that is having problems with shifting. It will shift in 1st gear and go in reverse( Makes a god awful sound shifting to reverse....) however nothing will happen once the RPMs get over 2500...Wont go faster than 30 mph... it will shift to 2nd gear however it will only maintain the speed up to 30 mph. The clutch was replaced less than 5,000 miles ago. Im not sure when transmission fluid was changed last just got the vehicle. Also it has a taillight out I tried changing the bulb no luck....Next place to check the fuse box? Any help on these two issues would be much appreciated. Thanks in advance - Dan
