1993 HT755 transmission check

[Bob & Carol Howald`]

I've just completed my over-view of my HT755. I dropped the pan and
checked the screen ( looked like new) . Installed a new temp. sensor
bulb. and cleaned everything up real good. (repainted the outside of
the pan). Installed a new gasket and filled with about 7Gallons of new
Amsoil Torque Drive Synthetic Transmission fluid. It's been about three
years since I filled with the Syn. fluid and I figured time was up and
it was time to flush the old and re-do with new. A fairly easy job, the
hardest part was getting the dip-stick tube out of the pan before pan
removal. I ended up using a 30 " pipe wrench to get it broke loose.
Total cost , less than $190.00. Bob 93pt40 Illinois

Bob, I appreciate your post, having just paid to have my transmission
changed over to synthetic fluid at an authorized Allison facility.
This included changing out the dip stick tube you referenced because
it had been previously bent/kinked to the point that it had a slow
leak. I purchased the new tube from BlueBird and furnished it to the
shop. I was less than happy with the service, which cost CONSIDERABLY
more than yours. I could see no evidence that the shop had dropped the
pan to clean the internal screen or that they had make any effort to
get all the old fluid out of the converter as they had stated they
would when I inquired prior to service. I asked the Service Manager to
follow up with his mechanic and give me a straight answer as to the
exact scope of the work performed but he has not given me a call back
as promised. Based on your input, I'll do the job myself next time.
