`94 Q45 transmission problem

[Bugzturbo]

I have a `94 Q45t that has an odd transmission problem. I actually bought the car to use the engine in a 240 swap, but wanted to drive it for a bit first. Problem is, after towing it home, the transmission seems to be stuck in gear (internally). No matter what gear you put the shifter in, it wants to go forward. It drives fine in forward gears, but put in in park and rev the engine and the car tries to lunge forward. It can't since it's in park, but it still tries. And in reverse, it just stays stuck and won't even rev up much since it's trying to go backwards and forwards at the same time. Can't even push the car forward or backward when in reverse, it won't move at all. I don't remember this being an issue before I towed it, but to be honest, I can't remember if I ever tried putting it in reverse either since I was more concerned with the engines running condition and it drive fine forward. Anyways, is there something electronic that may cause this, or is the transmission just fried? Not too familiar with these cars. Thanks

How'd you "tow" it? You can't tow the Q45 - the transmission's planetary gears get no lubrication if it isn't running.

On a tow dolly with the trans in neutral. Only went about 20 miles. Didn't think there would be an issue, I always tow RWD cars that way.

JATCO RWD AT will fail in 3-5 miles of slow speed rear wheel turning towing in neutral.....................worse in cold weather 2 miles may be too far.

We love it, always nice to get an extra $3,000 in revenue, usually happens when owners let fuel pump fail and then tow to shop.

Most Professional KNOW BETTER and have a danger list as they can be held responsible for improper tow proceedures.

So the trans is toast then? I could see if it burned something up, but why does it still work fine, just stays stuck in forward gear? The car still drives perfectly fine in forward gears. And as for the "know better" comment, that's all fine and dandy, but I'm not a commercial towing company. I just so happen to own a tow dolly for bringing home my projects. I guess I should hold the company that made the dolly responsible then since they didn't provide this "list"??

For the past 6 years here and 4 year prior to that on other forums I've discussed this very situation for Nissan RWD. Actually the situation began back in late 70's with Nissan RWD AT ------ 240/260/280/300 RWD.

Non familiarity with technology is no legal or moral excuse. Mechanical Murder is unfortunately not a crime just a fiscal one.

In ATL we've seen 4 different towing companies PAY for AT before a few drivers got fired.

Does it shift or is it locked in 3rd gear FAIL SAFE?..........a pan drop tells all.

Don't try the same with a Lexus RWD/AWD it will cost even more.

Only drove it around my buddies lot and down the street, but in forward gears it seemed fine, but I just called my buddy (it's at his place right now) and told him to take it for a spin and he says it does feel like it's stuck in a higher gear and couldn't get it to shift in the limited area he had to work with. So I would say it is in 3rd gear failsafe.

Norristown eh? Not too far from me I think. I'm over on Germantown by Lafayette Hill, Plymouth-Meeting, and Flourtown.

Yup, that's right down the road about 5 minutes.

It's nice to have another Q owner on NICO so close.

Here. Try the On-Board Diagnostic for the Automatic Transmission. Maybe it's something electrical?

http://www.nicoclub.com/FSM/Q45/1994_Q45/

That's the link to the FSM for your year. Check the AT section and pages 41-43. They give instructions on the procedure.

Page 62 also looks like it fits your problem. "Vehicle does not creep backwards when selecting R position."

Check it out.

Did you tow it or did you have it towed by a company? You know a company with deep pockets that you can complain to ?

Thanks, I'm going to try that this weekend if I can get over there. As for page 62, it does have that symptom, but those "check" require quite a bit of specialty equipment that I don't have access to. I'll try the electronic check though.

Towed it myself with a wheel dolly. Only person I can complain to is myself, and he doesn't respond well to complaints

I'll be headed back to Jersey for the weekend. Anytime during the week (Monday-Thursday) I'm pretty available if you need a hand.
