Improves shifting, reduces noise and shudder. Compatible with all ATF fluids, conventional and synthetic. Review: a truly brilliant additive - a really brilliant additive , my 2006 Volvo was having gear changing problems that a fluid change made no improvement on , but adding this made all gear shifts so much smoother with no nasty surprises Review: “Instant smoothness” - I decided to add this conditioner to my Vauxhall Antara transmission simply as an extra precaution because the reviews sounded favourable and the company’s exemplary reputation for specialists lubrication products is widely accepted. I was not disappointed as the normally reasonably smooth Antara transmission became velvety smooth after just a few miles.However,whilst I am not interested in the increased fluid life aspect of the product,as I change mine regularly, the benefits of the extra shifting smoothness are self explanatory with regard to the probability of increased transmission reliability and longevity. ## Features - Improves shifting, reduces noise and shudder - Compatible with all ATF fluids, conventional and synthetic fluids - Extends fluid life ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003JU71YG | | Best Sellers Rank | 300,046 in Automotive ( See Top 100 in Automotive ) 492 in Gear Oils | | Brand | Lucas Oil | | Brand Name | Lucas Oil | | Compatible Material | Automatic Transmission Fluid | | Container Type | Bottle | | Customer Reviews | 4.7 out of 5 stars 1,223 Reviews | | Global Trade Identification Number | 00049807104412 | | Item Form | Liquid | | Item Weight | 249 g | | Item weight | 249 g | | Liquid Volume | 1 Fluid Ounces | | Liquid volume | 1 Fluid Ounces | | Manufacturer | Lucas Oil | | Material | Synthetic | | Model Number | 10441 | | Number of Items | 1 | | Number of Packs | 1 | | Package information | Bottle | | Part Number | LUCA10441 | | Recommended Uses For Product | automotive transmissions | | Recommended uses for product | automotive transmissions | | UPC | 049807104412 049807804411 | | Unit Count | 591.0 millilitre | ## Product Details - **Brand:** Lucas Oil - **Item weight:** 249 g - **Liquid volume:** 1 Fluid Ounces - **Material:** Synthetic - **Package information:** Bottle ## Images ![10441 ATF Conditioner-591ml - Image 1](https://m.media-amazon.com/images/I/61wkM-AyuwL.jpg) ## Questions & Answers **Q: Do you have to flush the transmission to use this,or can l just add this to existing transmission fluid, thanks for the feedback** A: After 50,000 miles you should change your transmission fluid (and filter unless it's a screen type) if it's still bright red. But If it's very dark red or even worse black then flush the transmission it's money well spent to save your transmission. Keep in mind it will look like red metallic paint that's just part of normal wear. If it's bright red then just drain some transmission fluid to keep it at the proper level. Overfilling an automatic transmission by just a few ounces can cause it to leak. Best of luck to you. **Q: Does this work on a Prius?** A: I believe it works on any automatic transmission. Call Lucas Oil company to make sure and/or Toyota **Q: he can use on any transmission fluid?** A: Yes it's compatible with conventional and full synthetic transmission fluids note that this product is not compatible with CVT fluid **Q: do you have to drain any fluid** A: Check your fluid levels first, always! If it's full, or close, then drain the appropriate amount. 32oz bottle, drain 32ozs. Keep the old fluid just in case if you do a drain & fill on a trans that hasn't been serviced for 10+ years or over 30k-50k miles. That fluid may contain clutch material that's allowing everything to work properly, and fresh fluids can disrupt the fine fluid friction balance needed for an Auto Trans to work correctly. ## Customer Reviews ### ⭐⭐⭐⭐⭐ a truly brilliant additive *by G***3 on 15 November 2017* a really brilliant additive , my 2006 Volvo was having gear changing problems that a fluid change made no improvement on , but adding this made all gear shifts so much smoother with no nasty surprises ### ⭐⭐⭐⭐⭐ “Instant smoothness” *by M***L on 25 October 2020* I decided to add this conditioner to my Vauxhall Antara transmission simply as an extra precaution because the reviews sounded favourable and the company’s exemplary reputation for specialists lubrication products is widely accepted.
