Can any one tell me please whether you can change the shift seal on a super turbine 300 trans without removing shaft or trans from car.many thanks paul
This tool works on the 350 and 400 trans to remove and replace the seal. Should work on yours too https://www.napaonline.com/en/p/BK_...MIoM-p7deI6gIVPOaGCh3S0ARtEAQYASABEgIWQfD_BwE
OK, now we have something to work from & a few questions for you. I know that the 1st. year TH400 the piece connected to the shifter shaft was welded on & the ONLY WAY to change this seal was to drop the pan & remove the shifter shaft. Later year, 1965 & up the part was held with a 9/16ths. nut & the seal could be replaced by just removing the nut & the shift part. W ether it is the same on a TH300 I don't know, BUT it's not hard to take a look & if it's not welded on the tool mentioned makes the job much easier. Tom T.
