 Subject: overdrive working intermittantly
IP: Logged
Message:
All,
Need some help. I have a 90 dakota with 60k gentle miles and the overdrive has not been working intermittantly since about 48K miles. Seems to be getting worse lately. Any ideas? I did a search on alt.dodge.trucks and this seems to be a known problem with dakotas. But I could not find any conclusive repairs, everything from weak battery to tranny rebuild.
Details: 1990 3.9L v6, 3 speed with electronic overdrive, regular cab, long bed.
TIA

Same year Dakota but 4 times as many miles... however I can sympathize with this problem as I am experiencing something close to it as well. Mine will shift up into OD and immediately back down and this will keep happening till I disable OD with the button. I have not been able to narrow it down precisely yet but I have defiantly determined that that mine is related to what my tech is displaying... I have noticed lately my Tech jumps around allot (+/- 3000 RPM) as does the fuel gauge about ¼” deflection. When the tech remains steady and reads actual motor revs the trans works great but on the occasion (often) that it starts with its erratic indication's and I am driving upwards of 50MPH the trans will shift down out of OD just as if the motor really was revving that high every time the needle jumps up like I had just kicked it in. This tech fluctuation is just that, the motor itself remains steady Rpm’s. The fluctuation occurs from idol all the way up, aside from this annoying me so there is nothing else bad to say bout my Dakota! If you find out how to fix this or anyone else knows of something, PLEASE, PLEASE tell me!!! Thanks

Check the speed sensor on the trans mine went out and the speedometer quit and so did overdrive there is a gear that is plastic if it is worn it will cause some of this. The check engine light came on when mine went out and there was a code for it.

FYI
I replaced the battery about a month ago as it was not holding a charge well. I haven't had the overdrive problem anymore since then. The only other thing that has changed is that the days are getting warmer. I read somewhere that a certain operating temperature has to be reached before it shifts into overdrive.
