I would like to share a recent news release about the updated turbine half that we at JASPER provide on the GM 4L80E converter. This is just another example of how JASPER remanufactured products can offer better quality and performance, giving you longer vehicle life.
The update centers around a common problem where the fins pull out of the turbine. “Every one of the fins are bent over and staked to the inside, and the outside, of the 4L80E turbine itself,” says Craig Leuck, JASPER Transmission Division Manager. “Over time, and vehicle use, the fins will get loose, pull themselves out of the turbine, and make metal to metal contact with the pump half of the converter.”
JASPER brazes 100% of the turbine fins with a paste and a heat treating process. “Every one of the fins is brazed on the inside, and the outside, of the converter,” added Leuck. “This ensures the fins stay in place, and there’s no metal to metal contact.”
