2002 Infinity Qx4 transimission issues

[paluckinfinity]

Someone please help me! coming back from Tahoe yesterday (mountain driving conditions) and my car would not kick down into last gear. at 70mph i was sitting at 4k rpm's. It did this once a year ago for about 20 mins and never happened again. It seemed to work fine if i took the overdrive off. now when i went to pull my truck out this morning it would not go into reverse. I have no check engine or transmission lights on where should i start?

Oh sorry i searched the forums and read the posting guide i also live in northern california where usually it is warm but travel to in the mountains where it is much colder.

Did you check ATF fliud level and color? When was the fluid/filter last changed?

[paluckinfinity]

the fluid is a pinkish bright red so it looks ok. Flushed thed fluid and changed filter probobly a bot a year ago maybe 20,000-30,000 miles. Tried to back out of garage this morning and it is not going into reverse. Will still go into drive but not reverse.

how many miles are on the truck

Was the transmission shifting erratically or not shifting at all prior to this incident?

[paluckinfinity]

Transmission was fine before no issues. Truck has 140000 miles on it. Took it to aamco and they want to rebuild it think its a problem with my sun plate or disc somethin quoted me 2200-2800 for the rebuild is that a fair price?

I had mine completely rebuild for 2500 but mine burnt up a few gears

Then I found out you can score used trannies for less than $500 on Ebay, was pretty bummed

Id take it to another place for a second opinion though your problem doesnt sound to bad, when the levels are off in these tranmissions Ive read some funny stories, make sure its EXACT

AAMCO sucks- I would rather take a gamble on a low mile used transmission than have those idiots touch my transmission! Just google "aamco transmission reviews" and read up on the tons of unhappy customers.

Ya i didnt care for aamco much either found a local guy to do the rebuild and paid 1750 including some parts upgades
