Thanks, I might get me some of that Dr. Tranny.

My rumble strip issue only occurs when I'm in tow. I hate the sound it makes when it's about to get out of OD.

 

yeah mine occurred not towing, but will be towing the boat all next summer so even if this fixes it for now i'm still going to do a fluid swap like Mark mentioned in the spring.

 

That should work!
I don't recommend adding friction modifier. I recommend changing all of the fluid, using MERCON V fluid. That fixes about 95% of the transmissions that have this problem.

 

If yours is making that sound now it will be worse when in tow. I suggest you should get yourself an Edge Evo programmer, I set mine for the tran's option and really like it a lot, nice and firm shifting plus fuel economy increased.

Please report back if fluid flush really does the trick. But IMO these transmissions are weak to say the least.

 

You need a buddy with a warm barn, hoist, beer fridge, and tools.

 

yeah let me know if you come across such a utopia!

 

I know of one, but sometimes it's hard to keep the putz's out.

 

you said you had tools.. man you weren't kidding!

 

thought i would follow up and say the additive has completely gotten rid of the shudder. still definitely going to change fluid come spring, but for now it is better.

 

That's good news. The beer fridge and hoist will be ready in the spring!

 

Really! That's awesome and thank you.

How much of the Dr Tranny lube did you put in?

 

the whole tube.. which if i recall was only 2 ounces anyways.

 

Thank you, thank you very much. I'll be putting a few ounces soon, I hope I will get the same result as you.

 

Think I might try the additive, shop just told me that a fluid change would do no good, need an overhaul and new torque converter at 169,000 miles

 

for less than $5 it's worth a shot.
