Hi Guys, I have just had to open a new account while I contact a mod to get my dormant one reactivated.

 

I have had a 91 Z for 9 years and its been under cover for a year or two, Finally give it a spray a new engine and a mot about 6 months ago and shes back on the road., sort of.

 

On sat driving at around 40 the engine revved high and lost all drive in every gear, No reverse either.

 

First thought linkage but no thats fine. Will go into park and lock up but nothing in any other gear.

 

I have a good read through the fsm and dont think its anything electrical, Read the gearbox ecu and all clear on the codes so thats working.

 

I dropped the oil pipe to the cooler and checked for box pressure and there is loads so oil pump is working.

 

In all the threads I cannot find a complete failure like this,

 

I am now assuming mechanical not electrical so It s on its way out the car.

 

I am thinking either input shaft failure or torque converter but would love another opinion or have i missed something.

 

91 N/A auto import.

 

Thanks, Off to chase a mod to sort my old account out.

What was your old account name Matt?

Check the level of fluid and it's condition, it should be within range and a nice pink/red colour, brown and smelly is bad. There is a filter in the pan which can fill with particles blocking the proper working ability. The torque converter failed in mine, much the same as you describe but it got progressively worse, it would often be ok when cold then get worse.

Hi gary.

 

I have just been looking on how to send a pm. I don't know if it's because I'm on my phone but can't find it lol.

My old user is djmattamondo. Joined about 2007 I think. Had a paid sub for a year or two.

I had to set a new account as I could not post with the old one. Sorry.

If you could help me out I would appreciate it.

I will pay for a sub again as it was always a good help

Thanks

Thanks. I should have mentioned that although the fluid level was ok it was starting to lose its colour.

Drained it now and easiest way to explain the colour is I have seen a lot worse with no issues lol.

 

It's still the original box but I did change the fluid a few years ago. Sounds bad but I have not used it for several years.

 

It's half way out. Wow what a job.

 

Exhaust is a stainless one and had to take it off in one price. Cars only on ramps on the floor lol.

 

What are the 2 sensors near the cats. I assumed O2 sensors. Had to strip out the seats to trace the wires under the centre console.

 

Prop is off and just about to take cooler pipes off. Undo torque converter then bell housing then off she should come.

 

Brings back memory's lol. I thought changing the engine was bad lol.

The two sensors that come into the cabin are the catalytic converter overheat sensors, the other two higher up that plug in the engine bay are the O2 sensors. Take the starter off to access the torque converter bolts, undo turn repeat. It's a boring job pulling the autobox. Are you fitting another or are you going to convert?

Flagged your old account up for our admin guys to see if they can get it up and going again Matt.

Thanks gary.

 

As for what I do when the box is out is unknown yet. I will have a look around for a convert I think.

 

Yea done the torque converter routine before with engine change. Thanks

 

Beginning to think I should have lifted it all in one go rather than dropping the box lol

Really? I'd rather pull the box than the engine any day if the week.

Hahaha just on a break from pulling the top bolts from the housing.

 

Think I should have taken the plenum off

 

On both engine and box once the plenum is out the way life gets much easier.

 

Top bolts with the plenum on is a bit of a struggle but managed it.

 

Just the bottom few then pull it out. Sounds easy.

How did you do them? The two ways I see is from the prop end with about a meter of extensions, pretty easy or fight them out up close and personal. I personally take off my turbo elbows and starter and then there's loads of room, I don't recommend that though as often with most cars the elbows are seized on, mine have been off a few times now lol.

Accounts now merged.

Welcome back to the fold mate!!

 

Richard:cool:

Ahhh matt is back. Thanks for sorting the accounts. Reminds me of my past. Went from owning bars and clubs to indoor go karting lol.

So for anyone following this thread in the years to come.

 

The box is out and unfortunately everything looks good.

 

Still oil in the torque converter and nothing looks out of place.

 

I still have not come across anyone who has had the same problem. Complete loss of all motion.

 

Taking the box to a local gear place tomorrow for his opinion. A rebuild is out the question as it's over a grand.

 

I just want his opinion on the torque converter. It's still my best guess as to whats wrong.

 

Looking around now for a n/a auto box or maybe a manual convert if anyone knows anyone who has any. Just about to check the forum.

Derek in enniskillen northern island has one , contact him via the forum.
