Hydromatic Trans

[Fla truck]

Hi Dr. Lee,
I have a 93 GMC 6.2L with an hydromatic trans, on a plate i saw the markings KD.P.
What should i be looking at to have it rebuilt, and would it be cheaper/better to buy a remanfactured transmission at Autozone?
I have 191,000 miles the truck was my fathers and now i have it. It runs fine now but when a relay went in the trans, the mechanic, gave me an estimate of one year more on the OD gear... well more than one year and 30,000+ miles later, I am wondering what to expect. The estimate I was given for a rebuild landed in the 5000.00 range...
thank you

Does the transmission have four ranges on the shift pattern, 1 2 D OD ?

Is the transmision pan almost perfectly square? If yes to both of these, then you have a 700R4 or a 4L60 transmission. In 1993, it might be a 4L60E.

In Florida, the place to go is Fourth Gear Inc., just north of Orlando. See them on the web at

and check the prices. Don can arrange for local installation for less than $500.
