OD Light

[xyelloxxstarx]

Okay so I'm a girl and I know some general stuff about cars but I've been learning since I've been reading these posts - but I still need help! I bought a 93 Jepp GC Laredo 4x4 about a month and a half ago. He said there was a problem with the overdrive but I bought it anyways for a nice price hoping I could fix it. Worst case scenario- the tranny hasta be rebuilt.
Problem is this: The OD light doesn't work at all. Whether you push it or it gets up to gear, it doesn't work. It also has problems shifting from 1st to 2nd unless it's been running for awhile. It'll kick up to over 2800 rpms shifting from 1st to 2nd and then kicks back to down to normal. Unless you keep accelerating, it'll kick back down and back up again.

I was wondering if that had something to do with the overdrive and if something could be done without replacing the tranny? I've heard stuff about fuses and sensors etc. If anyone knows anything it'd be alot of help! Thanks!

this from another post on here

I think when people bring thier Jeeps in to shops, mechanics first
think MECHANICAL failure which equals big money in their pockets. These
Jeep transmissions are controlled by a computer and therefore has
electronics to support this. I bet 95% of people that bring in their Jeeps
for a $3000 replacement just need an electronic part changed out.

Here is my example: My 95 Grand with 4.0 and 2wd now has 270,000 miles
on it. I've dropped the tranny oil pan many times and changed the
filter and oil. The one thing I do that I believe is as affective as a
"flush" shop is disconnect the rear cooler line, attach clear plastic hose
(you can buy at any hardware store), start the Jeep and shift to
neutral. This sucks up the fresh oil you just filled in the pan and pumps
old fluid out through your clear hose into a bucket. When clear oil
flows out of the hose your done. Don't forget to keep adding oil so that
you don't suck air. A buddy can help out with this.

Back to my example, recently my transmission started "slipping".
Salvage wanted $1500 installed with 90 day warranty (for used trans that
would last me 91 days I'm sure). Dealership quote was so high they were
yelling it at me as I was running out the door. So I looked harder into
my problem. In reality the trans would not shift into second until I
hit exactly 38 mph. I repeated this over and over. started internet
research and determined it had to be an electrical problem. Bought OEM
governor pressure transducer and solenoid (electronically controlled
items let me add) for $300 and now I'm back to a like new transmission.

All I'm saying is before taking the trans in for a rebuild make sure
you don't have something wrong with the electronics. Good Luck! Chad
