Gear oil like no other

My Nissan 370Z 6 speed REV match transmission has always has a lazy synchro shifting into 2nd gear and so you learn to double shift when the car is cold (not up to operating temp). Z forms have often talked about this with 350Z & 370Z. The Nissan dealer using an Ester 75w90 synthetic oil and I have had them do the oil changes. A friend told me about Red Line oils and I thought I would try MTL 75w80 in the transmission last month, Oct 2020. OMG! What a change in operation, so smooth and that 2nd gear shift character was gone...gone like shifting into 3rd or 4th. Thanks Red Line great product, just change the Diff with your 75w90

I read a lot of great reviews on this product and it did not disappoint. Shifting felt butter smooth. Shipping arrived right on time, packaging was top notch and included stickers since touch. Overall a very positive experience with PI and their product! Definitely look forward to ordering with PI again!

What a Company!

Amazing business to purchase from, I’ve bought gear oil from Performance Improvements before and will continue to do so. Fast shipping every time and product is exactly what was ordered. I had a clunky/grinding NV3550 and the Redline MTL I purchased did just the trick! Thank you P.I. Speedshops!

Great OIL

Thanks for the very fast shipping. Price is better than amazon and shipping is faster. Oil Redine for my tranny is a must to have. This synthetic fluid will help my tranny to shift better. Thanks again to Peformance Improvements
