I Just Bought A Really Neglected Q45 *Help?!*

[clouhd_nihne]

Bought a 1990 Q45 about a week ago.. The transmission fluid is black and I really don't know what to
do... It slips into neutral when I'm driving and wont go above 35mph. I'm thinking of changing the fluid and filter? The speedo and odometer don't work either, and there is already 198k on the car:/ (I don't have a manual for this car so if anyone has one or knows where to get/buy one I would be VERY greatful:) I would LOVE some oppinions on this as there is alot I dont know about this car.. thank you!:)

deff change your trans oil and filter, and also use the search function it took me all of 3 seconds to find this.... http://www.nicoclub.com/FSM/Q45/ i know 1990 is not shown but im pretty sure they are all the same

[clouhd_nihne]

kay, but is it worth it? or should I get a whole new trans?:/

[clouhd_nihne]

and is the manual for a 1994 the same as a 1990? I found that before but I just wasnt sure:/

[Heavy]

um i would try the fluid and filter first, seeing as a trans is prob somewhere in the 1k+ range

[Oatmealman]

Unfortunately if the trans fluid is black your taking a risk by changing it as it can wash away all the friction material thats just hanging out.This is more of a problem with trans flushes but Ive seen it happen to extremely neglected transmissions.You don't have much to lose though so id give it a shot and if it doesn't fix it its time for a trans rebuilt and if it does drive the car and change fluids on a regular basis.

[Jesda]

Just do a drain and fill of the ATF. Dont flush it.

[clouhd_nihne]

ok:) thank you:)

Try a bottle of the Lucas trans fix. Awesome stuff. Ford used to make horrible transmissions but one bottle of that trans fix would have it working great.

[breadbox]

have fun with Q once it scoots.

I suggest a 50% fluid change to start out.

Drain all the fluid into a clean catch container.

Change the filter.

Put 50% of the old fluid back in + 1 bottle of Lucas and 50% new fluid.

I have rebuilt an automatic transmission before. The friction material on your clutches is going to be very worn and that abnormal viscosity old fluid is helping the friction material function. If you change it all your going to buy or rebuild that transmission in 5000 miles or less.

Here are worn clutchs

If you're looking to possibly replace the trans anyway might I suggest this...

5 speed swap, just sayin'.

[gwoods]

Change the fuel filter too!

I bought a 91 sunbird blown head gasket for $100. rebuilt the topend and it would not shift into second on full throttle or go past 70 mph??? The fuel filter was so clogged it was starving the motor. Changing the fuel filter fixed all the 'transmission' problems.

[clouhd_nihne]

I cant drive a stick but thank you anyways:) and I think I'll just do that 50% thing:) I paid $600 for this car, I was just wondering if thats an O.K. price?

[jbracy7]

600 buucks yeah thats fine some tlc some good labor it will be fine

[clouhd_nihne]

kay:)

Seriously? Time to either learn or turn your man card in. If you can drive a stick shift you can drive anything with wheels.

[naladude911]

idk how to either

[Razi]

idk how to either

We know.

[breadbox]

Broad statement.

[ADDirishboy]

idk how to either

We know.

I would definitely try the 50/50 trans mixture, and replace all the filters, including the fuel filter like gwoods stated. If it's been neglected that badly your filters are gonna be clogged up like crazy. Changing them should do wonders for you. If you're still having issues with the trans slipping into neutral after you do all the work, then start looking into a rebuild.

[AZ89two4Tsx]

That picture scares me, lol. Automatic transmissions make my brain hurt.

clouhd_nihne, if you can't do the work yourself, I would just get rid of that thing asap.

Old luxury cars are basically money pits. There's really no way around it.

Ummm ... when you drain an Infiniti Q45 transmission (i.e., without using a powered flush system like a B&G that cycles the gears), then all you get is about 50% to 60% of the fluid out in the first place. I.e., there is no need to "put 50% of the old fluid back in" as far as I know.

The presence of a dark transmission fluid usually means it was never looked after ...

My suggestion echoes Jesda's. But if a simple drain and fill does not improve the situation, you have a dead transmission. You will need to rebuild or replace it ...

I dont have a man card:) lol im girl:) welp, I'm going to try and fix this stuff soon! but if im not able to I'm just going to probably sell it as a parts car:/ Thank You everyone for all of your input:))

Very large recent influx of females on teh formus.

Well, if you learn how to drive stick, you'll have more of a man card than Nala. I know you don't know who that is, but trust me, that's not a very large accomplishment.

Hope everything goes well with the Q. They are quite a joy to drive when running properly. There might even be some people on here who can help you find a good, reputable shop around the WA area that isn't gonna charge you an arm and a leg for some simple stuff, or better yet, someone who could help you learn how to work on it! Good luck!

Nala's man card only seems to show when girls are drunk and passed out. Remember the ending scene to the movie 'Kids' when the dude is banging the passed out girl with AIDS, that's Nala. Welcome to NICO.

That's actually saying that Nala would get that far with a passed out girl with AIDS, It'd be more like Forest Gump when he touched his first boob.

[Rev_D21]

You're right! But you must admit that Nala has a 98% chance of contracting AIDS during his first sexual experience.

Probably, and Nala would likely be proud to offer that up as proof he got laid. There is no vaccine for his stupidity.

I think you have a win-win situation with your Q. If the fluid change works, you have yourself a nice vehicle. And if it doesn't work, you should be able to recoup your investment as a parts car.
