Transmission additive.

[GeorgeS]

I own a 2005 Ford Explorer with 98K miles. At 79K miles I had the transmission serviced @ my local Ford dealer. Since that service the transmission has delayed or harsh reverse engagement. I returned to the dealer for service. They recommended replacing the solenoid body ($1,000). Does the transmission additive need to be replaced when the transmission is flush?

Welcome to this forum! I've moved your thread to the transmission section. The dealer wants way too much for this repair. You could do it yourself for a fraction of the cost. Which additive do you want to put in? Many different additives are on the market from Lubegard, Lucas, etc.

BrooklynBay, Thanks you for your response. What and where should I purchase the solenoid pack? Does the new solenoid pack need any additive? I read the TSB 05-21-8 requires an additive to the transmission or is that not required with the new part?
Do you think that replacing the solenoid pack will fix my delayed and/or harsh reverse engagement?
Should I have the pressure gauge test done? Please advise.

You could connect a 0-300 PSI gauge to get some readings. The solenoid blocks tend to act up around 60K miles. The price on the solenoid blocks went up recently. Here's a link: http://800700tran.com/prod.itml/icOid/159

nice, I just purchased a pack two weeks ago for a full trans rebuild, always nice to save a few bucks!

Brooklyn, I have read many posts recommending an additive - I decided on the lubeguard green bottle(I think)
I see very few posts on oil type and upgrades.
My 5r55w uses mercV - which I believe is a synthetic oil.
I had my parts disributor at my shop deliver new atf - he brought mercIII.
He thought it was all the same - the second time he brought wolf's head super uni.
All the searching I have done shows good reviews. While I can not find it directly from amalie, who blends wolf, I did find this....stating the wolf oil is a true synthetic 4 or 5 base - http://www.lubritecinc.com/PDF/2008synatf.pdf
I am not sure if motorcraft is 3,4 or 5 group.

Here is my question.
Is/If the wolf super Uni(or others such as amsoil,mobile1) is superior to the stock oils(motorcraft mercV in my case)....is an additive still useful or benefitial?

inquiring minds want to know.

Lubegard is the only OEM approved additive so it can't hurt to use it.
