MikeRL411 Posted February 23, 2015 Report Share Posted February 23, 2015 For RL411 and early 510 owners with the British automatic transmission, JCPenny is having a sale on the filter and pan gasket kit. "OE Replacement A/T Filter Kit Mfr # REPM313901" Whitney SKU JCW-1025510. $14.21, free shipping. There is a floating discount code as you sign in to the site JCWhitney.com so look for it. Last Saturday it was 10% off but an e-mail offer was 20% off. If you have this transmission this is a chance to get one or more for the future. 1 Quote Link to comment
MikeRL411 Posted February 28, 2015 Author Report Share Posted February 28, 2015 Got my kit today! I will let you know if the good fortune smiled on me or if I got dumped on with the site part number! If nothing less at least the pan gasket looked to be the right one. Quote Link to comment
MikeRL411 Posted March 3, 2015 Author Report Share Posted March 3, 2015 Well wouldn't you know, this is not the British Borg Warner kit. Back to the search. My local Nissan dealer has located what appears to be the right kit, due in in 2 days. 1 Quote Link to comment
MikeRL411 Posted March 5, 2015 Author Report Share Posted March 5, 2015 AutoNationSouthBay Hawthorne CA came through with flying colors! Kudus to service advisor Bob Spencer! The correct transmission filter and pan seal is a [are you ready for this] a 1974 Volvo 144 kit, part number J5010-15927 ! Perfect fit and function since Volvo used the exact same British Borg Warner transmission. In and working like the charm it is. Quote Link to comment
datzenmike Posted March 5, 2015 Report Share Posted March 5, 2015 That would be the Borg/Warner 35 built in Letchworth England plant built in '56 and expanded in '60. They supplied most of Europe's automatics. This model had no cooling lines but used a finned torque converter to 'air cool' themselves. The case and the bellhousings were cast iron usually. Some 510s got the Letchworth made BW-35 but there were at least one other model 35 made in Muncie Indiana that did have cooling lines. After April '71 Nissan had their own 'in house' automatic from JATCO Japan Automatic Transmission Company called the 3N71B. Quote Link to comment

My Letchworth built British Borg Warner [RL411 version] definitely does have the external transmission oil cooler in the radiator! Earl's in Lawndale just made me a replacement set of hard line engine block fittings to radiator flex hoses and they work just fine thank you. Oddity, most USA fittings are even numbered, the British Borg Warner installation via Yokohama uses number 5 fittings. The 510s had either a M35 or a T35 and I don't know which was Letchworth and which was Muncie Indiana. Quote Link to comment
datzenmike Posted March 5, 2015 Report Share Posted March 5, 2015 One things for sure. There is an exception for everything. :lol: My info shows a cable kick down on the Letchworth and vacuum on the Muncie. Quote Link to comment
MikeRL411 Posted March 5, 2015 Author Report Share Posted March 5, 2015 One things for sure. There is an exception for everything. :lol: My info shows a cable kick down on the Letchworth and vacuum on the Muncie. Absolutely true! BTW, never lubricate or mess with the length of the cable. If the length is altered there's a major and potentially dangerous alignment proceedure that involves tapping into the hydraulics and reving the engine for a VERY short time to measure system pressures. Not for amateurs, professional transmission mechanics with a death wish only. Quote Link to comment
MikeRL411 Posted March 8, 2015 Author Report Share Posted March 8, 2015 If anyone insists on swapping out the British Borg Warner transmission and needs to go through the alignment needed, PLEASE info me for the correct realignment and hardwire kickdown proceedure!
