A generic powertrain (engine and transmission) trouble code, same meaning on every brand.
Yes with care - expect a limited or fixed gear range.

Read P0755 yourself before paying for diagnosis
A basic Bluetooth OBD-II scanner ($20-40) plugs into the port under the dashboard and shows this code with live sensor data on your phone - useful both for confirming the fix and for talking to a shop from an informed position.
What is going on and how it gets diagnosed
P0755 covers shift solenoid B. Automatic transmissions produce their gear ratios from combinations of solenoid states, which is why the failure of a single solenoid rarely removes one gear cleanly - it usually scrambles a whole set of them.
That is worth knowing when comparing symptoms to codes. A car that has lost second and fourth but keeps first and third is describing a single solenoid failure quite precisely, and the pattern often identifies which one before anything is disassembled.
Repair options and cost
Typical US independent-shop ranges, parts and labor. Dealers run higher; regional labor rates vary.
Owner reports mentioning P0755
“2002 rav4 ecu shifting problem (dtc code p0755). The car jitters when switching from gear 1 to 2 as well on reverse. It also jitters when it drives on low gear. There is an well known problem with rav4 2001-2003 but toyota has failed to recall it, despite being a safety hazard as it has caused accidents and bodily injury. It has the high likelihood to destroy the transmission.”2002 Toyota RAV4 · Aug 2019 · 129,000 mi

“After 148,603 miles on my 2002 rav4, the transmission began shifting back & forth between 1st & 2nd gear with violent shaking. Shifting from drive to reverse also caused violent/loud clunking. A scanner was used to retrieve trouble codes which yielded a p0755 code (shift solenoid malfunction). Upon research on various toyota rav4 forums I found many others with same symptoms. *tr”2010 Toyota RAV4 · Sep 2010 · 148,603 mi

“Experiencing transmission problems (jerking & slipping) with my 2001 toyota rav4. Took it the northway toyota dealership in latham, ny. Was told that ecm needs to be replaced ($1300) and potentially a transmission ($3400). Taxes and labor are to be added. Googled dct (error code) p0755 obtained during the checkup and found toyota's technical service bulletin tc002-06 from march 3rd, 2006 describing this problem and indicating the need to replace ecm. This repair would have been covered under toyota federal emissions warranty (96 months or 80,000 miles). Why toyota did not contacted me to let me know about this problem in almost 4 years making me to pay almost $5000 for their mistake? *tr”2001 Toyota RAV4 · Dec 2009 · 92,000 mi
“2002 toyota rav4, 4wd,at transmission jerking and hashing, reporting code p0750, p0755... I called toyota dealer in portland, or and speak to master technician. I've been told by the master tech that rav4 2001-02 and 2003 rav4 needs a new updated ecm for about $800.00 + labor. He warned me that without replacing the new updated ecm, my rav4 transmission will be damage and it could cost about $5,500.00 parts + labor. Toyota warranty only 8 yrs or 80k miles since this is their flaw software programming and why don't they do a recall campaign to eliminate the possible safety problem. Instead they only notify their service center of their dealership. Please help rav4 owners.... *tr”2002 Toyota RAV4 · May 2009 · 115,000 mi
“GOES INTO LIMP MODE. Transmission shifts hard, slips, locks up. I've been having this issue for 2 years. Transmission seems to shift twice in 3rd and 5th gears, there's a jult then goes to limp mode, no excelleration. After a minute or so, it's stuck in 3rd or 5th gear. Wrench light appears. I have been pulling over, ( when it is safe ) plugging in my scanner, then erasing codes. P0755, P0740, P0741. This has been a temporary fix. I've had the valve body replaced 3 times, with the lead frame. And recalibrate to the ECM. Still having the same issues.”2015 Ford F-150 · Dec 1969
