My transmission removal & rebuild
#21
Does anyone else have rusty subframes on their cars? The edges of mine in certain spots are rustier than I care to see. I scooped some POR15 and went to town with a tiny hobby brush. I focused on the front subframe arms and the rearmost bar of the front crossmember/cradle assembly.
Here is my thread on it: https://www.jaguarforums.com/forum/x...member-199299/
Thanks for sharing your transmission replacement. I'm hoping I don't have to do it in the future. My car is pretty jerky around town when just puttering around, but pulls hard when I get on it. I'm hoping its not a transmission problem, but I haven't investigated much.

Restored the front x-member in my XJ40 with POR. At the time, the dealer thought it was a new one installed. Your x-member will now be there long after the car is gone. Years of road salt will not affect the POR. You have to grind it off to get it off. Great stuff.
Progress goes on.. The trans is in. This was one of the easiest transmissions to line up and bolt in, even with doing it by myself. My makeshift wood & duct tape trans jack worked great
I also rebuilt one of my brembo calipers - what a disaster. The seals I bought made the pistons too tight and they got stuck in the caliper. I ended up using the old seals for the smaller 2 pistons. PITA!
I should be finished up this week..... My transmission mount is broken and leaked blackberry juice everywhere. Im waiting for another one to show up.

Transmission mount is in, transmission fluid is in (took 10.5 quarts) I used Mercon SP.
The old transmission mount was oil filled. some nasty black stuff came out of it. The new mount is an all rubber design and much beefier
I went into SDD and cleared the adaptations and took it for a spin.
Transmission is extremely smooth, and shifts wonderfully. The engine feels incredibly smooth, that mount must've been bad for a while.
the 3-4 shift is occasionally met with the squawk noise on up shift. SERIOUSLY??
I just started driving and have only put 10 miles on it, so ill be monitoring closely. I wonder if the adaptations will slowly adjust the shifting...

Small update.
My rebuilt transmission has 'The Lurch' - It never did this before the rebuild. Im beginning to think the Mercon SP may not be up to the task with this transmission.
The 3-4 squawk is still there, albeit much less then before the rebuild.
I'm trying to scoop up more LG6 fluid and flush as much Mercon SP out as I can.

The squawk and lurch only occurs when transmission is fully warmed up (aka driving 10+ miles) Hot florida days definitely aid in warming up the transmission faster.
I agree this doesnt seem like a fluid issue, however Im at the mercy of the shop who built the damn transmission, and they are saying that Mercon SP isnt correct. Ive dropped the car off to them so they can replicate the issues.
I know they are gonna tell me to flush the trans out and put LG6 in.. Id rather them just do it so i can come back later and show them the noise is still there.
Or I could be wrong and maybe the LG6 will solve all of my life's problems?

Sounds like you just may have chosen the wrong shop to do your rebuild.
Sad state of affairs when people either have no idea of W T F their doing.
Or worse yet they do, and just do a poor job.
Blame anything, or anyone, for your mistakes, or fork ups
What are you going to do, just how can you prove that they are wrong, hire a liar?????????????
Main reason i learn to my own work, i trust NOBODY, i can't watch do the job.
To them it's another chore to accomplish before time to go home, but I have to live with it!!!!!!!!!!!!!!!!!

I was under the impression you do that with SDD while driving.
Also what is the sate of your transmission now?
