Thank you so much for sharing your insight, this "weak reverse" issue was driving me nuts... Do you know that feeling when you're driving your truck and you know something isn't right, and you just can't take it out of your head?.

Where in North GA you at? I might throw you some business your way. My OD is not working on my 03 Expedition Eddie Bauer. Everything else works fine

hey jk080....you seem to have a lot to say about tranny's/ i thought i would run this by you

i have 05 expedition. reverse works great. revs and barely pulls in first. i am not sure if it will shift into second yet. could i be so lucky to get through this without replacing or rebuilding tranny.
thanks

First off let me say that I have read several of your posts and though you would be the person that could help me with a problem I'm having with a 06 fx4 5.4 litre I just bought. When i test drove it it ran great but today I noticed it seemed to be shifting funny from 2-3 and 3-4 on light acceleration, like it was going into neutral. Well since the person I purchased it from said it had a transmission warranty on it I took it to the local dealer to find out this has been an on going problem to the extent that its had 3 new transmissions installed,they even removed the trans. from my truck and installed it into another truck where it performed perfectly,all the pressures checked out with no codes. They suggest trying a new PCM, so I'm trying to do some research before I spend another grand on it. I should also add that when you turn off the OD it shifts out fine. Any help would be greatly appreciated.

Hey jK080
Your a master trans tech why don't you give me some advice on the thread Iposted
under RM 109 5r55e OD servo. I don't why I haven't gotten any advice maybe it's to complicated
sure has me stumped. And no novice

Hello, jk080, I picked up my truck today and the hard shifting has been eliminated. They ended up removing the pin inside of the modulator, then re-installing it and re-connecting the vacuum line. Shifts smoother than ever. Any thoughts?

Thanks for the info. The drummer in the band I'm in is also the maintenance mgr for the city and services all the fleet vehicles (police, etc.) I asked him to take it for a spin and he agrees. Said to take it back on Friday and leave it until it is fixed. He also suggested I take it to Aamco, drop his name, and ask them to give it a spin and if they think it is something that can be adjusted. We'll see. I'll let you know what the outcome is when this process is complete. Again, thanks for the info.

Hi, jk, just joined the crowd and I have a question for you, if you don't mind.

I just had the automatic transmission in my 94 Mazda B3000 3.0L rebuilt and it hard shifts from first to second gear. All other gear shifts are smooth. The guy at the shop said that the hard shift would disappear in a day or two. What are your thoughts on this shift problem and on the statement made by the shop personnel?
