No reverse (update: transmission failure)

[mario65]

I know this is old but if you dont put the trans filter bolts exactly where they came out and you accidentally stick a long one in a short hole youll blow reverse in the valve body.
SO if you do a trans filter be careful to put screws exactly where they came out

Turbo to answer your question he is ASE Certified and mainly services Euro Imports (Porsche, BMW) but also does maintenance and repair of Japanese imports too.

He has been using OEM tranny fluid.

What we do know is that there is some sort of seal leak...he was able to detect an intermittent pressure drop when on reverse. As far as a Lucas additive was concerned the product description does state it would help with seal leaks:

Transmission Fix – Lucas Oil Products, Inc. – Keep That Engine Alive!

As I mentioned previously, we replaced the oil and seals, filter , replaced the Valve pistons, replaced valve body, and problem persisted.

So short of a new tranny, we decided a hail mary pass of the Lucas tranny additive.

So far it seems to work...it doesn't hesitate to go in reverse (knock on wood). I will continue to observe for any hiccups.

BTW, perhaps it was a coincidence that we asked for a tranny fluid flush prior to the reverse issues popping up. How likely would there be accidental damage from just a fluid flush?

Thanks guys!

hi, my transmission is currently doing all you've described. Did the Lucas transmission fix make a difference?

Hi there:

Nope. It turned out we needed to rebuild the transmission. Lucas transmission fix was only temporary.

The so called independent mechanic ripped us off. Upon an inspection from our transmission mechanic (He is a former Toyota mechanic who did all the transmission jobs) valve body was not replaced.

In the end we bought a rebuild kit from transpartsonline.com

Hope it works out for you.

Thanks for your response. I'm sorry you got ripped off. It's quite unfortunate and a darned shame how awful people can be.

Sorry, I have to bother you with more questions. Would you say that if they had actually replaced the valve body, it could have saved you the rebuild? For how long was the Lucas transmission fix able to keep the transmission going? In the long run, do you think adding Lucas may have contributed to needing a rebuild or was rebuilding the transmission inevitable from the onset?

Looking forward to your response again. Thank you
