It is a 8 for a novice and that is if there aren't any problems and you have the tools. You can also engage 1st through 4th and then manually turn the transmission to feel for problems.
Volvo m41 laycock overdrive install#
You might just have to bike the bullet, and install the unknown M41/ODs into the car, and try them in-situ for a while.thankfully, it's not that difficult to perform the swap.kinda heartbreaking if results are negative, sure.but that's the way it goes.sometimes you get lucky, sometimes you don't.that why they make vino.īesides the visual checks you already mentioned, you should check the magnetic drain plug for each 4 speed section and the filters in each overdrive. but in your case, the OD would have to be separated from trans, to be tested in this way, so trans would remain an unknown. It's certainly worth making a few phone calls to the British car specialists. Sure you can inspect by pulling trans cover, and you can wire up the OD Sol out of a car and apply power to see if that works, but without spinning it up, and going through the gears + OD under load and at temp, it's not really possible to check things like bearings or OD function.I did hear of an OD specialist at a big British swapmeet, who set up a special teststand (with I expect an electrically powered motor), to with which an OD could actually be bolted, and spun-up, to functionally test, including operating pressure of pump.I expect those are somewhat rare, but if you were really lucky, an Laycock OD specialist near you might have one and can offer the same service for a fee. Let me know if you need any more information or have any other questions. If it turns out the transmission or overdrive needs rebuilding the $100 is applicable toward the rebuild work. We charge $100 per transmission to do this checking/diagnostic service. We have the proper gauges to check the internal oil pressures both in overdrive and non-overdrive. We would also engage the overdrive and test the solenoid with our battery. We have a test bench on which we can spin them up at 1,000 RPM and go through the gears. If there is no apparent damage visible in the inspection then the next step is testing. If you bring or ship us your transmissions and/or overdrives we can inspect them and test them to see if they are functional or need work.įirst we would pull the covers, magnets and filters and see what is going on inside. Yes, we can help you out in your dilemma. Seems like the best solution for me.Īnthony - Hi and thanks for your inquiry. They are about a 45 minute drive from here.
