Couldnt hurt. Would be cheaper than springing the $ for a rebuild/repair if not needed.

I had forgot about this old thread I had started. You know I never added the Lucas to the tranny in this old Pontiac, but I still have it. I havent driven it in over a year though. The PS hose started leaking and I parked it. I put on a new hose about 4 months ago and moved it to another part of the driveway, covered it with a car cover and its not been touched since. Its a shame I am leaving it setting, but I have too many other cars that are more practical, but I dont want to part with this old Pontiac. I may get it out some this summer on the weekends.

Dont put that Lucas tranny fix molassis in anything you intend on keeping. I lost two transmissions with that crap. The fact it barelly pours out the bottle is an omen not to add it.

I have an 07 town and country minvan and the transmission just started that "whining" sound. It drives and shifts just fine but I don't know what the whining means or if I should just drive it the way it is and not worry about it... or buy some sort of additive and see if that stops the noise. Need a bit of advice.... thanks

Many, many people swear by Lucas transmission conditioner and I am one of them. My wife refuses to part with her 2005 Freestar (2 in college another just got of grad school). Ford replaced the torque converter at 100k (warranty) and at 145k the trans started to slip. This ford trans is notorious for failing early. Any way it's been 10k without another slip in the trans. So yes, it Definatly works, but I would never sell it out right to a private party just in case it failed on them. If you google it you will find on many different forums about people useing it for slipping trans.

Have it looked at and fixed. I can't remember what year, but one generation had bad transmissions, the last K-Car models, I believe.

If it's whining, I'd point towards torque converter, not transmission. TC goes at very high RPM. I am not sure if Lucas will fix that. About the only other possibly whining part in AT is high pressure pump.
Otherwise, I am big Lucas fan.

You can hear the engine speeds change, but you cant feel the shifts (and no its not slipping). This has been my experience with ALL cars I have had with the Turbo-hydramatic 400 (GM) of the late 60s-mid 70s.

With that out of the way, I took ownership of my 1973 Pontiac 9 years ago. The day I took possession from grandma the transmission has had a "whine" in first gear. When it shifts to second, it goes away. I changed the fluid and filter last year and it didnt change it.

It has done this for NINE years and has never failed me. I was told it sounded like the pump was getting weak, but NINE years of driving with this whine, it must last a long time when its weak. Now its getting to where I am annoyed by the sound and wondering if LUCAS transmission additive would help tone this sound down, or is it only good for leaks and slippage, which neither are things this tranny does. It dont slip or leak, only has the whine.

Wondering if its a waste of money for the Lucas or should I live with the whine from 1-2 gear?
Smooth shifting transmissions is not good from what transmission guys have told me. A firm shift is what you want a barely noticable shift point is a sign of trouble.

I took it to a transmission guy who said the first thing would be to change the filter (which is in the trans casing).... it might be getting plugged up. I will try that first and see what happens.... thanks for the feedback....
