Detail: Replaced broken pump shaft and converter splines at 65000 miles, at 82000 miles the transmission slips at every start. The pump was replaced under warranty. Is it reasonable to relate the slipping of the transmission to the broken pump shaft such as contaimiation or inproper installation?
Detail Question SOLVED: Replaced broken pump shaft and converter splines a

Solution: Might be but it is difficult to speculate about what happened 20,000 miles ago. Dirt in all its forms shorten the life of an auto transmission, unfortunately the transmission produces much dirt for itself so it will eventually self-destruct. Boy-racer starts, towing, long slow hills, heavy slow-moving traffic and suchlike are all things that cause the tranny to create more dirt and hasten the end. When a tranny gives mechanical trouble best practice is a complete strip-down and a thorough clean every time especially when a close examination of the oil pan reveals metal swarf - the big problem is the extended downtime and a great deal more expensive than most owners would tolerate and so repairs are carried out instead, hopefully striking the correct compromise between the cost and the life expectancy. I suspect the auto tranny technology hasn't kept pace with engine technology as in my experience they are failing earlier and in greater quantity than ever before and in my limited experience 82,000 miles isn't so bad... A broken shaft and damaged converter splines would certainly produce metal swarf and best practice would be to completely dismantle the transmission for a thorough clean but as the work was under warranty it is unlikely that happened. , Hi, a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

Goodluck! , I would have your speed sensor checked out as they can send a false signal to the computer to make it think that the tranny is slipping and / or the torque converter is failing. Good luck and remember to rate all the solutions you get. Thanx. , do u have any transmission trouble codes? u should if the OD light is flashing, the light flashes to alert u that a electronic malfunction is occurring in the trans controls, u may just have a bad trans connector or a shift solenoid starting fail due to a shorted field closing coil. , Perhaps the Transmission mount?? , I would have the transmission check if you plan on keeping the car a long time. The lucas oil is an additive for the oil. The additive is making the fluid a little heavier and tricking the soleniods or clutch and bands with a different pressures. This is a temporary fix. The transmission over time is going to start to slip more and more. , its the speed sensor on the transmission. usually at the rear.
