And "main valve body : At this point, any other expert comment, something in there that I would have missed, and possibly caused the "teeth salad" ? M.

This week-end, I opened also the two clutches, just to find there that all disks looked in good condition, or at least not burnt. But damages to the teeth there also, on the rear clutch gear : and shaft :

Thanks Harvey, would this be with the Valve body, or the clutch pack itself? I apologize for the poor quality its my first try at video's. On the 1st Video the air test the first one is the front clutch, and i do hear a faint thud of the front clutch during the test. the other tests look good as well. Please let me know if you see anything i missed here. In the 2nd video I am not sure what tube was loose but other then that everything looks good. Unless you notice something. Thanks again. Next is a closer look at the valve body, then pulling the box.

This is becoming a really confusing thread and it's a pity as left untarnished it's an excellent instructional tool for those who want to learn something about BW35 automatics.
It appears there's 2 posters simultaneously querying individual problems. I can't see how this would benefit either individual as it just confuses clarity of purpose when attempting to resolve the issues.
Why not (Admin)lock the thread where it originally concluded with Andy's excellent rebuild information and have the individual 'posters' create their own threads thus removing confusion/overlap and saving the 'intent' of this original post.
PS: Both Individual Posters. I assume you both have work shop manuals. A comprehensive manual should list each and every spring and it's specifics for a particular valve body. I believe Harvey has pointed out there are many valve body configurations for these boxes. Each have specific spring types fitted to the various valves. There is also a range of front servo pistons of varying sizes. Muddle any of these servos, springs and valve bodies and you have an enormous head ache. Some of these boxes have a rear pump and the associated valving in the valve body. More things to muddle. Your manual or any manual on the BW35 will have a chart illustrating what elements function under specific shift positions. This will provide you with most of the answers you require.
One of the valve bodies presented for appraisal looks as though it's full of sludge/silt! Valves do stick and jamb on occasion, so a clean valve body and smoothly operating valves should be one of your first assessments.
I'm not trying to be on anyone's case, but there doesn't seem to be much system in the approach. You need to look and investigate each component/unit/valve/spring and eradicate that component/element. If you have fragmentation of components in the box your first task would be to....?

Dear Enigma, You are definitely right regarding the thread. I feel really sorry if I introduced any confusion. => Being the last one in, I'll move my posts to a dedicated thread, this way will not bother you and others here, nor take the risk to waste this excellent one (in any case, anyone wishing to focus on the complete rebuild and so rich inputs and hints from Andy and Harvey - thanking them again here - may do so, by reading only pages 1 to 12 ...).
Regarding the "comprehensive manual", certainly it would contain all details, for all types of BW35 with all types of valve blocks, pumps, servos and everything. Unfortunately, I am afraid I have not yet found this comprehensive version : would you have any recommendation where to find one copy ? Again with many thanks, and sincere regards M.

You won't find any one book that covers everything about the BW35.

Micmadox, no apologies required. I just believe that diluting Andy's comprehensive BW35 rebuild thread compromises its value as a learning tool for those wanting to fully rebuild their own gearboxes. Starting your own dedicated thread will provide you with comprehensive answers that will not be jumbled in with someone else's gearbox issues. Most libraries have a range of technical manuals for borrowing. The BW35 and its upgraded derivatives (BW40, BW51) was fitted to an enormous range of cars throughout the world from the 60s to the late 80s. Eg. Ford, Volvo, Chrysler, Wolseley, Rambler, Rover. I found the most useful source to be the Ford factory workshop manuals not the smaller aftermarket non factory manuals.

Harvey, Thanks a lot for this clarification that there is no comprehensive documentation.
Following on Enigma's point, there is a lot of documentation available, either generic BW35 or specific to one or other make.
I have on hand, either originals (paper) or copies or digital versions of :
- one "Model 35 Automatic Transmission Manual" from Borg Warner Ltd (pink cover)
- the Rover P5/P5B WS manual, two versions,
- one Daimler V8 - BW35 manual,
- one SIMCA 1301S Automatic - BW35 manual (in French),
- one SIGMA GE WS manual - Section 21b BW35 ,
- one Volvo Automatic Transmission BW35 manual.
If can help anyone, please just let know.
Don't have the Ford one mentioned by Enigma : any place to find it on the net ?
And if some members are interested by a Spanish version, there is one on eBay at the moment (article n°261621724927).
M.

This comprehensive, generic BW35 Manual should provide you with more than enough detailed rebuild and diagnostic information. BW35 Comprehensive Manual PDFVery useful, thanks for the link. I'm fortunate to have the original box in my car without anyone having interfered with it over the years.It functions as it should but there are two niggles which, to some of you guys, would take 5 minutes to sort out. The kickdown doesn't work and the selector linkage needs adjusting to allow starting in "P" Both issues require underside access. Problem is that I don't have any facilities to work on the car and there's not a level bit of ground to be seen so I can't SAFELY get under the car! In addition, I don't know anyone in the Plymouth area with either the knowledge or the facilites. Very frustrating because I can turn my hand to most P5 things if I've got access.

BW35 Comprehensive Manual PDFFrom a quick scan through the above PDF, I've seen there's a pretty crucial error in there, and I can't say why it's there. Whether it's been a printing problem, or it's been introduced by whoever uploaded it I have no idea, but the consequences of that mistake could, or rather will, cause real problems, and if there's one error, there could be a load more..

Truly amazing Harvey! If you've spotted an error in the PDF which to all intents and purposes seems to be a reproduction of a factory publication why not make the necessary reference and correction/citation rather than allude in cryptic terms to unsubstantiated errors which ultimately assist no one but only place the seeds of doubt in those wanting to repair/restore their vehicle. I don't get it!
Open quote.
Quote Post by harvey on May 5, 2013 at 11:54pm. (Page 9 of this thread) You need to do the front band adjustment again. You need a 1/4" spacer in place not 1/8" or so that you used, and then once that's set you fit the spring so it's backed off two turns, which is roughly 1/8". You've only done half of it, the only reason you set the adjuster that far out in the firstplace is so that there's enough room to get the 1/4" spacer in, but so the head of the adjuster is still visible so you get the spacer in the correct place. Torque it up on the 1/4" spacer, then wind the spring fully on, and back it off two turns. Alternatively dispence with the 1/4" spacer, torque the adjuster, then back it off 4 full turns. End quote.
Alternately...Dispense with the spring adjuster completely. Slacken the adjusting screw locknut, move the servo lever outwards and place and place a 0.25 in. gauge (1/4" spacer) between the servo piston pin and the adjusting screw. Tighten the adjusting screw to a torque of 10 in. lbs., tighten the locknut and the remove the gauge block.
Note: If a small tension wrench is not available (or not within your kit) a cheap spring balance can be utilized. To obtain the correct reading for the spring balance divide the Ib/in setting by the spanner pull length, eg. 10 lb/in divided by a 4 inch spanner pull = 2 1/2 lbs. (Hook the spring balance on the free end of the spanner at a right angle and pull till the indicator of the spring balance indicates the appropriate tension)

That ( page 64 of the P.D.F , page 62 of the book itself ) was the page that I used when I set the front servo on this build thread, which as Harvey pointed out at the time was wrong, and the correct way to set it up was described in detail. I think I send you that page at the time as well Harvey, it caught me out, so no doubt it will do the same to others, but at the time it was the only bit of information I had regarding the setting of the self adjusting front servo.

Jens, I also done a few engines and gearboxes and motorbike engines and also open to new challenges but when i had problems with my BW35, i decided not to do it myself as i believe, you need a fair bit of special tools to overhaul a BW35. I choose to buy a 4ZF box from Andy (eightofthem) which is a different approach. He also rebuilds BW35 at a fair price, complete with an overhauled or new torque converter. I believe you cannot beat his price when you do it yourself. My attitude is that when it worth overhauling something, it is worth to do it good and i find this thinking in his work. It is a detailed overhaul Andy does, with all new bolts, a clean and neat housing and he supplied me bits which i hadn't thought of. His shipping charges are also low and if you need advise, he gets back very quickly. I don't have shares in his company but believe that when people do a good job, this should be shared. Peter

Interesting Peter. I was not aware that Andy offers this service, but I will certainly get in touch with him. My main reason to get into the transmission itself, is that I will soon have the engine out for rebuild and the torque converter is misbehaving. So when it all comes out of the car, it was my intention to at least install new seals and check if anything else like brake bands and clutches are approaching the end of their lives. The transmission shifts OK. I am certainly aware of the price having just overhauled an MGB gearbox. Although it is manual, very simple and the initial problem was just the notoriously failing 2nd gear synchronizer ring, it added up before I was done. Thanks, Jens.
