1995 Toyota Tercel SLUGISH
I believe that what you are experiencing is whats called FAILSAFE MODE, which means its stuck in 2nd or 3rd gear due to recent change in driving habits.... maybe you got on the accelerator a little too rapidly or sharp corner too fast.... All, Nissan's, Toyo's, and most cars have this mode wich is meant to prevent further damage to the trans. This may not be what your experiencing but it sounds like the symptoms, sluggish, slow acceleration,.......have you experiencs and shifting issues, is it an auto or manual trans? if you have a trans power or over drive button and or light on dash or shifter for automatic, observe when you start it up next time and you may find it blinks 8-10-12 times.... if so you have damaged the trans due to mismatched/mixed tire sizes and or tread depth, and brans or tread styles.... yes it doesn't just ruin 4x4 auto trans,.... it kills any transmission after unknowingly driving around with incorrect tires. I work for Nissan and have for 26 years and i have seen chain tire dealers like Walmart, Sears Roebuck, Midas, Tire Wharehouse, Pepboys, and dozens of others cause the transmission planetary-gear failure; in mostly automatic 4x4 or AWD vehicles when replacing just one two or three tires AND NOT THE COMPLETE SET AS REQUIRED BY EVERY AWD AND 4X4 AUTO MANUFACTURER. DON'T BE A VICTIM... BE A WISE CONSUMER.... AND GET AN ATTORNEY IF YOU BECAME ONE ALREADY....THANKS AND GOODLUCKTransNissPro
