NEW! GM 4L80/85-E 3rd & Reverse Checkball Sleeve

Excess wear in the 3rd and Reverse checkball sleeve in GM 4L80-E and 4L85-E transmissions leads to multiple shift issues, burnt direct clutches and ratio codes. The new Sonnax 3rd & Reverse checkball sleeve 34200-38 will restore normal shift operation and protect against unwanted premature wear for maximum life. No reaming or special tools required!
