Castrol Transmax High Mileage Automatic Transmission Fluid, 1 qt

2000 GMC 1500 I have always had an issue with the tranny doing a pause jump into gear sometimes, could not determine why or exactly when. Dealer could not find issue. Now after 95K miles I swapped out fluid with this and after months now everything is smoother and no more issues.

I have a 2000 Honda Accord with 218,000 miles on it. I was experiencing hard shifts when accelerating moderately to WOT on the highway. I was skeptical this product would have any effect. I bought a gallon and did a drain and refill. Amazingly, the transmission shifts much smoother! The gear changes on the old fluid caused the car to lurch forward. Now it's a smooth transition. Would definitely recommend!

Having a little torque shudder in a 2000 Silverado. Tried other torque converter additives, they worked for a little while then shuddering came back. Decided to pull a quart of the old fluid and replace it with Castrol, and now it is working fine. My plan is to replace 1 old quart at a time as needed. The truck is very old with over 250K miles, don't want to do anything stupid. So, far, so good, no more shuddering from 40-50 mph.

I have not used product yet

Excellent product. Cleans %26 tightens shifts back to new. Even @ 245K miles.

I replaced conventional oil with castrol transmax high mileage because of hard shifts. The situation improved gradually and after several years of using this my transmission works close to how it should. I have now 350,000 miles on my 2004 Impala. GM transmissions typically give out long before 350,000 miles. With Walmart's price on this I see no need to try less expensive products. Highly recommended. I put a drain in my transmission pan and do a drain and partial replacement on a yearly basis. It is easier than taking it to a shop for a total replacement with a flush.

it is a good brand why i gave it a 4 star i havent used it but a great price
