this part is hard to get to . you ll have to disassemble the trans to get to it. if you ve never worked on a tranny before , i d suggest not even attempting to do it. i d take it to a qaulified technician.How hard is to replace a thrust washer?
Drop the crank.
Which one? There are two in the 440T4. One is at the very bottom of the case under the final drive, the other is on the top of the input housing under the input housing thrust bearing
It requires disassembling the trans partially ,and this requires someone with trans experience
if u mean throw out bearing..u have to remove tranny..thats the hard part.
