    I have a '02 Tacoma Xc Prerunner with a 3.4 v6 motor. I have an Interstate battery approx. 4yrs old.I found that one of the cells were low so I filled it with distilled water. Then I noticed that the starting revolutions started to slow, telling me that the cell is probably week. I have no problem replacing the battery but here is where I'm stumped:I noticed that the transmission doesn't want to move the truck till it idles for about 5-7 min. then all is ok. So my question is this. does the transmission have electronic components that the weak battery would cause to lose memory? I hope I've explained my problem well enough.

    explain what you mean by the transmission wont move the truck. I dont believe a weak battery should make a differance.

    Weak battery by itself, probably wont cause problems. Low voltage from a weak alternator and a weak battery will cause problems, but you'd have more than trans issues. I would say you need to have the charging system tested aa well as the trans. 80% of shifting issues can be fixed without removing the trans. Valve body issues usually cause shifting problems.

    Well it seems that the weak battery will cause electrical problems in the 2000 Tacoma Prerunner, I found that after replacing the weak battery with a new one the transmission problem went away immediately. There seems to be a solenoid on the transmission that regulates the amount of pressure produced by the torque converter and allow the trans. to move the vehicle. As to what exactly it was that I meant as to the trans. not moving the truck, when the truck was finally started and put into drive the trans. would have a slipping action the same of that of a trans. that had the bands of the first gear we're slipping. Again the new battery resolved this problem. Thanks for the responses. I inadvertantly said it was an '02 when in fact it was a '00 sorry.
