Need replacement transmission for 87 300TD
My 300TD trans has been downshifting at highway speed to third and sometimes second for the last couple weeks. Finally brought it to the dealer for diagnosis. They claim it is the governor, and the trans needs replacement. I'm certainly not going to pay the $7500. they are quoting, and after reading horror stories about Ads..co.com, I don't think I want to chance $1750 with them on one of theirs. Anybody put there have suggestions on where to get a reliable rebuilt one at reasonable cost, or have any experience with places like Aamco?
Thanks, J.G. |

I have one that worked fine when I pulled it and replaced with a 5 speed. It needs a front seal as it leaks but worked just fine. $200+ shipping. Might be able to ship it cheap on Greyhound.

If you want to go with a rebuilt, Sun Valley has an excellent reputation. I have not purchased from them but am considering doing so for my 95 C280.

I also have a slushbox sitting in the garage from my 300d. It was rebuilt by the previous owner a couple of years ago with receipt. I should probably put it up on CL.

Why not pull the governor and inspect it? Maybe the worm gear is bad?
I pulled mine from my 92 300D - is it the same for the '87 300TD? |

If it's the same as the one I did - it's not that bad. You push the transmission to the side and pull the governor cover off and pull it out.
There is a plastic worm gear that sometimes breaks and causes issues with the higher gears. |

replacement transmission
I have used Sun Valley. I ordered one rebuilt about 6 years ago was a great deal and I am still driving it. was very reasonable for me, was 1.500 and that was shipped to RI from CA. not bad at all. worked great. not advertising here but was the best deal I could find.

if the governor was bad the trans would not shift out of 1st or if it was stuck in an open position it would lock out the lever in N and prevent shifting into R.
Your problem sounds like something the valve body is making it shuttle between the two speeds. I read about this problem a long time ago here on the forums, the person had to partially disassemble the rear part of the valve body and clean out an internal screen. Cant recall exactly what it was.

Try going for the low hanging fruit first: See if you've got a faulty/sticking kick-down switch under the accelerator pedal. Try unplugging it. Also check that the wiring to that switch is not shorting out.
Good luck.

Your transmission will be similar to the one shown here =>
722.303 in bits photo shoot But I guess there'll be more plastic parts in the back end...
